7 Month Old Baby: Development, Sleep and Milestones

The most intensive growth and development of the child’s body occur up to 1 year. The future mental and physical state depends on the successful passage of this age segment. The body is most vulnerable and susceptible to disease in infancy. He needs special care.

Hereditary mechanisms programmed the growth rate, weight gain, and maturation of organs and systems at each age stage. Under optimal conditions, these processes proceed according to a certain plan.

The impact of unfavorable factors (nutrition, upbringing, diseases, etc.) contributes to violations of the sequence of development, which are often irreversible. Knowledge of the characteristics of the growth and development of an infant is important for recommending adequate regimens of life, nutrition, education, disease prevention, etc.

7 Month Baby Development

7 months is a new stage in the development of the child. The baby becomes more sociable and inquisitive at this age stage. He sleeps less and shows more interest in games and knowledge of the world. Significant changes continue at physiological and psychological levels. We will describe the most significant moments in the development of a child of 7 months.

It's The Size of
a Strawberry

Based on length and size of a baby at 10 weeks pregnancy we can compare it to strawberry.

It does not feel like anything yet inside your belly, but structure is there and soon enough it will grow big.

10 Week Baby Size

How Heavy is it?
0.15 oz ~ 4 gr

Bone structure and enlargement of head has made our baby at least to double in weight between week 9 and 10.

Slowly growing baby fetus is now at 4 grams or 0.15 ounces. Keep in mind that every baby weight during pregnancy is slightly different.

Baby parts development summary

The sense organs are aggravated in a child at 7 months. He uses them more fully than before. The child hears perfectly and sees well, but his vision is still improving. There is an intensive development of the brain. The work of the digestive system does not stop improving. It changes with the introduction of complementary foods, becoming more adaptive and enzymatically enriched.

The first teeth erupt during this period. This is a good indicator of correct development. The baby strengthens the musculoskeletal system and improves a sense of balance.

Brain – The parietal region of the brain is actively developed. In the visual and parietal cortical zones, the volume of pyramids increases, and intercalary neurons develop. Changes in the structure of the projection and non-projection parts of the brain are progressing.

CNS – Increases synaptogenesis. Nested groupings of neurons appear, which contributes to the improvement of information processing. All analyzer systems are included in the familiarization with the outside world. The number of new neural connections increases.

Digestion and organs of the gastrointestinal tractThe transition to a mixed diet is accompanied by a sharp activation of the secretion of hydrochloric acid and pepsinogen. It is a precursor to pepsin that aids in the digestion of proteins. The mass of the stomach increases due to the increase in the muscle layer.

Jaw and teethThe first lower and sometimes already upper incisors erupt. The gums become red and inflamed where the teeth appear. Salivation increases. The shape of the skull changes due to a change in contact between the jaws.

Muscles – The muscles of the trunk are quite mature. Constant crawling strengthens the muscles of the back and lower back. Leg muscles are still relatively weak. The primary task of the child is to control his body through developed muscles.

Heart – The volume of the heart increases. The increase in its size is mainly due to an increase in the volume of the left ventricle. The hole between the atria is overgrown. The heart gradually moves to a vertical position.

Your Baby Growth at 7 month

The seven-month-old child has noticeably grown and grown stronger. He no longer gives the impression of a defenseless creature. His muscle mass has grown, his height has increased, and the proportions of the body have been harmonized.

Weight and height may differ from the standard accepted norms. Babies will be born with smaller growth rates if there was a multiple pregnancy. Another growth parameter is a head circumference. This figure will be 43 cm for girls 7 months. For boys – 44.3 cm. The girth of the chest in seven-month-old girls is 43 cm and in boys, it is 44 cm.

7 Month Old Baby Milestones

Now the child is well developed physically. He masters new motor skills and his coordination of movements grows. The baby is improving in control of his body. He perfectly strains the muscles and can resist and give a small rebuff.

There are significant shifts in social communication and mental development. The child strengthens his memory and cognitive functions of the brain. He can perform simple tasks. Associative links work well. Here are examples of the most important moments in the progressive development of a child of 7 months.

Visual and auditory communication The nervous structures and connections responsible for the quality of sensations are fully formed at this stage. The kid has already learned to connect the visual and auditory range, realizing that they can have one source. The child will try to manipulate the toy if it makes sounds.

The child distinguishes the mother’s voice well and begins to look for her face. The relationship between visual and auditory orientations is close and productive.

Physical skills and abilities The child can rise to all fours and begin to crawl in this position. He swings in an emphasis on his knees, practicing to crawl. The kid is actively practicing sitting down on his own or is already sitting down from a prone position.

The child makes alternating stepping movements if you support him by the chest. He can kneel firmly holding on to a support.

Improvement of fine motor skills The child holds the toy well at 7 months. He shifts her confidently from hand to hand, examining and manipulating her. Often knocks with a toy on the floor or other surface, analyzing the sound emitted from the force of impact.

The child sits down, which expands his visible space and contributes to the better development of his motor functions. The development of coordination capabilities contributes to the manipulation of objects and deep familiarization with the outside world.

Expanding the functionality of perception The ability to highlight the shape of an object develops. The perception of form gradually begins to prevail over the perception of size.

This feature is since in the second half of the year there is an intensive maturation of posterior associative structures. Their neural apparatus is aimed at recognizing complex images. The child gives preference to new objects and toys, remembering them precisely in shape and color.

Understanding speech A child at 7 months responds to his name. The kid turns his head towards his father to the question “where is dad?”. The baby mirrors the intonation vibrations of the voice of the mother and loved ones. He may burst into tears if someone screams in his presence.

Progress in speech perception is recommended to be directed to the mental development of the baby. He already clearly associates the names of objects with their appearance.

Skills in processes A 7-month-old baby grasps a mug or a drinking bowl with water, tilting the vessel. He reaches for the spoon, trying to hold it and direct it to his mouth. Such skills are poorly developed at this age but are already beginning to improve.

The kid can repeat the movements during the game that he is shown. It also imitates the speech and sounds of animals.

The developed motor reactions of the child become an integral form of adaptation to the external environment. The basis for cognitive activity is a sharp increase in independent actions.

The development of motor functions and associative connections improve brain function. The child is easier to process the information received during the day. This is facilitated by its comprehensive perception. Speech develops well at 7 months and expands the child’s communication capabilities.

“Babies 7 months old are very different. Some are already able to speak consciously simple words and others are not.”

7 Month Old Baby Health

The introduction of new doses of vaccines is not included in the standard vaccination schedule of 7 months. Consult your pediatrician and immunologist if you missed any of the vaccinations. They will evaluate the effectiveness of administering vaccines at this age.

The use of vitamin D as a health and nutritional supplement is recommended. It should be in an easily digestible form, combined with a quality diet and sufficient calcium. Vitamin D deficiency is manifested by subtle symptoms: increased nervousness, lack of growth, excessive sweating, and flat skull.

Iron deficiency anemia can sometimes develop with errors in the introduction of complementary foods in babies 7 months old. Closely monitor the nutrition and condition of your child.

Sleeping Schedules at 7 Month

Daytime sleep time is reduced from 7 months of age. The kid wants to fit less and less but resists and continues to play. Wake time is increasing and significant shifts in the sleep schedule are likely. Night sleep is a little stabilized. The number of awakenings is reduced. The duration and number of naps may change.

The daily norm of sleep at 7 months is 13-15 hours. Sleep at night should take at least 8 hours of this time. Daytime sleep is reduced to 3-3.5 hours. Sleep schedule during the day may vary. Some children sleep 3 times, someone is already switching to two naps. Consider your child’s characteristics. Most often, there is one long sleep (1.5–2 hours) and two short ones (30–40 minutes).

7 Month Old Sleep

7 Month Old Sleep

Be guided by how your baby initially slept when drawing up a sleep schedule. Perhaps at this age, two long periods of sleep will be enough for him. Compensate for the lack of daytime sleep with a short rest if the child always sleeps a little. Always alternate active wakefulness with sleep. Do not force your child to sleep.

Bedtime becomes more difficult at 7 months. Don’t delay this process. Try to apply early sleep at night. Remove all toys in advance and create a calming atmosphere so that the baby begins to mentally prepare for a night’s rest.

7 Month Old Feeding

You can replace part of the breastfeeding if the baby eats solid foods well. In the case when additional nutrition goes badly, the child eats little and refuses fruit puree or cereals, then it is better not to deprive him of breast milk.

Egg yolk is added to the diet at 7 months. It is a rich source of vitamins B12, A, phosphorus, and selenium. Gently introduce butter in small portions and vegetable oil without refining. The diet of the baby should be different vegetable and fruit purees, cereals, and cookies. Do not overdo it with snacks, otherwise, the child will refuse the main meals.

Breast milk or adapted formula can only be left for breakfast and dinner with good use of complementary foods by the baby.

7 Month Old Baby Movements

The duration of dynamic loads in a seven-month-old child increases and their endurance to them increases. The nature of the interacting muscles changes: a balance is established between the flexor and extensor muscles. The movements of the child are not precise and unstable. A feature of the age under consideration is the formation of objective actions. The kid performs simple manipulation actions with toys and cutlery.

A 7-month-old child knows how to: crawl, sit, pull up and rise slightly, squat, and reach for an adult in his arms. The active formation of all structures and systems of motion control continues. The musculoskeletal system is developing. All this is aimed at overcoming gravity and mastering bipedal locomotion.

Safety Around Child

The second half of the year is a period of a significant breakthrough in the baby’s motor activity. Now he is already able to conquer heights. The child reaches for objects, tries to climb obstacles, and actively explores the space around him. Such significant developmental progress requires parents to pay even closer attention to the child.

There must be a complete reorganization of the spaces in the house for the safety of your child. It includes the rearrangement of furniture, the installation of special protection on cabinets, doors, and windows, and the installation of fences.

A kid can injure himself with sharp objects, spill boiling water and get burned, or fall from a great height in the process of learning the world. Teething causes gums to itch. The child puts everything in his mouth. It is dangerous for foreign bodies to enter the respiratory tract.

2 Month Old Sleep

Pets – No matter how harmless pets may seem to you, it is better not to leave them alone with your child. Do not rule out an aggressive reaction to a child who may grab a dog or cat by the tail.

In the apartmentInstall special protection on the door that will help avoid pinching fingers. Mount stoppers on windows and nightstands. It is better to remove the handles from the chests of drawers. The child can pull himself up on them and knock over the chest of drawers.

Swimming pool – If you have a private house and have a swimming pool, immediately fence it off so that when crawling, the child cannot fall into the water. Always keep the baby in your field of vision.

Changing tableIt is better to stop using the changing table if the child has become too active. Don’t leave him alone. This will reduce the risk of the baby falling from a great height.

Sockets and electrical appliancesClose all sockets in the apartment with special plugs. Keep cords out of child-reach areas. Switch on electrical appliances only for direct use.

First aid kitKeep all medicines, tablets, syrups, and other medicines away from the child’s eyes. Better to keep them locked up. Poisoning by pharmacological agents is a common occurrence among infants.

What To Schedule Next

The next vaccination is scheduled for 9 months of age. You can pre-book to re-administer Hib and IPV vaccines. It is worth consulting about the possibility of introducing a flu vaccine. Most often it is done from 6 to 15 months.

A scheduled examination by a pediatrician is required at 7 months with the measurement of the main parameters of growth and development. A visit to the surgeon and the neurologist according to indications is possible. Registration for kindergarten is voluntary. Choose a certified facility that can provide infant care.

Parents Tips and Development Speed Up

Never try to change your child by following accepted norms. All children are individual in their development. Learn to perceive the baby as a separate person with his habits, whims, and well-established biorhythms. Use only proven advice and recommendations from specialists in the field of pediatrics.

  • Do not force him to walkThe longer the child crawls, the better for their health. Do not provoke upright posture earlier than nature intended. The muscular frame at 7 months is not strong. Walking must follow walking at the support.
  • Stick to a dietDon’t mess with your child’s diet. Stock up on food and breastfeed while traveling. Keep intervals between meals no more than 3.5 hours. Don’t overdo snacks.
  • Supervision – Leave the child exclusively with an adult, well-known and healthy person. Do not appoint older children as nannies. Giving responsibility will not make them adults. Your baby should always be supervised.

Since your baby has sat down, his possibilities have expanded significantly. The circle of his vision increased, his hands were freed, and the body was leveled. The child can now be included in more diverse games using their hands. Get new educational aids and intellectual games for your baby.

5 Ways to Speed up Development

  1. Cognitive abilities – Read books with pictures, poems, and use flashcards.
  2. Fine motor skills – Actively use sensory development boxes only under supervision.
  3. Intellectual development – Collect pyramids, sorters, and puzzles. Show animals and people.
  4. Emotions – Speak emotions: “you are upset”, “you are in pain”, “you are scared”, and “you are tired”.
  5. Physical activity – Encourage your baby to crawl. Arrange the toys by lifting them to a height.

Your child is growing and developing at an unprecedented pace every month. It is necessary to provide the baby with attention, care, love, and affection for the successful flow of all development processes. Praise him after every small success. Encourage when he calms down and help him get out of tantrums. Always remember that you are the adult in the family, but a child is also a person.
