11 Month Old Baby: Development, Sleep and Milestones

Scientists and physicians have been studying the key moments of a child’s development from birth for many years. The data helps identify standard growth parameters that pediatricians use to assess infant health.

Most of the established average statistical norms of growth and development are conditional. But a serious deviation from them speaks of pathologies and developmental delays. Knowing all the subtleties of age-related changes is necessary not only for narrow specialists, pediatricians, and psychologists but also for parents.

From 1 month to 1 year there is the most intensive progress in the development and growth of the child. The foundation of the baby’s psyche is laid during this period and the most vital morphological transformations of the internal organs take place.

Baby parts development summary

Important changes in the growth and development of the internal organs, systems, and parts of the child’s body occurred during this period. The intensive formation of all structures of the motion control system and the development of the musculoskeletal system continue. This will be the basis for new transformations at subsequent stages of development.

The maturation of brain structures and improvement of the departments responsible for speech and cognitive functions takes their course. The volume of the brain grows the size of the heart and stomach increase.

The structure of the brainThe overall structure of the brain is approaching a mature state. Myelination occurs in most fibers of the cerebral cortex. The bark is divided into layers. The cerebellum grows rapidly. Its mass increases almost 4 times.

Gastrointestinal tractThe shape and size of some organs of the gastrointestinal tract are changing. The funnel shape disappears and the esophagus is gradually formed as in an adult. The mass of the stomach increases to about 0.6 oz. He is in a vertical position. The descending part of the colon is lengthened. The mass of the liver doubles.

Chemical composition of bloodSlight fluctuations in the number of erythrocytes are observed. Their lifespan is increasing. The amount of hemoglobin in the blood increases. The albumin level rises. The composition of the blood is relatively constant. The number of lymphocytes continues to decrease.

Teeth – By 11 months, the baby has up to 4-8 new teeth. The upper and lower lateral and central incisors should already erupt. This is the norm for children under 1 year old. Delayed teething occurs in 25% of infants.

Skeleton and spineThe beginning of upright walking leads to the appearance of lumbar lordosis. The center of gravity shifts. The vertebrae are stretched out. Non-fixed curves of the spine are formed, which disappear after muscle relaxation. The upper ribs begin to take a horizontal position.

Muscles – The muscles of the back, lower back, and pelvis is strengthened with an increase in physical activity. The abdominal muscles are well developed. Increased strength in the muscles of the lower extremities. Increases overall muscle mass. Structural transformations of muscle fibers occur.

Your Baby Growth at 11 month

The growth parameters of an 11-month-old baby do not undergo major changes. The child grows according to the genetic plan. Weight gain is slowing down. The indicators will differ if there is a hereditary tendency to obesity or low weight gain.

The average head circumference of a girl of this age is 45 cm, and that of a boy is 46 cm. The chest circumference also remains at the same level. Girls are 45 cm and boys are 46 cm.

11 Month Old Baby Milestones

The baby is approaching its first year of life. His growth slows down a little during this period and achievements in cognitive activity begin to progress. The kid actively develops speech, explores the world, and interacts with others.

Serious work is underway to master walking. The child is already confidently standing, which expands his view and accelerates the effectiveness of obtaining new information. The kid can learn from mistakes, analyzing the wrong steps and actions. Let us consider in more detail the main points of a child’s development at 11 months.

Communicative activity Communication becomes an important tool in understanding the world. The child closely follows the behavior of an adult, constantly attracts attention, reaches for his hands, and babbles. He is already prioritizing: he is more committed to interacting with his mother or older children.

The kid is more and more interested in his peers. The child reaches out to other children, tries to play with them, and reacts emotionally while on the playground.

Means for indicating desires The kid used to resort to only one way to show his desires – this is crying. Now the variety of funds is very wide. The child can point a finger at the desired object, and say the word “give”.

He understands well the words of approval. The baby may nod his head if something is wrong. Some babies already know how to say no.

Active development of self-service A child of 11 months more and more wants to do everything on his own. He can take a spoon, try to feed himself, and hold a cup or drinking bowl on his own. Holds a piece of fruit or a cookie and eats it. He repeats some of his mother’s activities: combing his hair and putting himself to sleep on a pillow.

Many children are easier to dress because they deliberately put their hands in the sleeves, and pull their legs to put on tights.

The first fears appear The baby reacts suspiciously to unfamiliar surroundings. He may start crying at the sight of the doctor. He is worried about approaching the hospital where he was once given a vaccination or an unpleasant procedure. The brain perfectly fixes the object in which the child experienced severe discomfort.

Children start to be afraid of strangers. They are embarrassed, hiding behind their parents, and crying. Sometimes strange things scare them: fur on a jacket, a new toy with sound, a vacuum cleaner.

Development of concretization skills There is more correct processing of information. A child of 11 months is capable of generalizing concepts. He knows what “let’s go to eat” means. The kid understands the words “toys”, “animals”, “street”, and “house”.

Many children can distinguish and remember colors at this age. If the mother tells the baby: “Give me a green cube”, he will give it. Concretization is expressed in the separation of general concepts from specific ones. When asked to give a doll, the baby will give the doll.

Pronunciation of monosyllabic words The kid replenishes his vocabulary with simple words, in addition to little intelligible babble that only mom can make out. Now the child can name family members in a simplified form, some animals, objects, and requests.

Monosyllabic words have a bright intonation color, which shows the direction of the spoken sounds and words. There is the intonation of indignation, delight, fun, and anger. The child’s speech is replenished with new sounds and combinations.

Children at 11 months become more active, mobile, and developed. Now psycho-emotional development is predominant over physiological. The child shows a need for communication, establishes socialization processes, and takes serious steps in complicating play activities.

Significant changes in the work of the nervous system are noticeable. Emotional responses change. The first fears appear, a steady resistance to the undesirable and a demonstration of character.

“A child of 11 months is not required to walk and talk well. Development is as individual as growth.”

11 Month Old Baby Health

The imperfect functioning of the immune system puts 11-month-old babies at risk of contracting viral and infectious diseases. Babies suffer from the Epstein-Barr virus, SARS, and conjunctivitis of various origins. Digestive problems may appear as flatulence, constipation, and diarrhea.

Pay close attention to how the baby’s legs move and the foot is fixed when he begins to walk. A timely visit to an orthopedist can save you from many problems. Enter vaccines by age: Hep B, Hib, IPV. Continued intake of vitamin D3. This vitamin is especially important for proper calcium absorption and strong bones.

Sleeping Schedules at 11 Month

Gradual transition to one daytime sleep begins at 11 months. This significantly changes the overall sleep schedule. The periodic loss of one of the sleep constantly shifts the time of bedtime and awakening. Parents are required to maintain schedule flexibility.

An 11-month-old infant has a reduced total daily sleep time. It is now 12-14 hours. Sleeping during the day is 2.5 hours. The baby will not sleep exactly this time every day. It changes and can be divided into two shorter periods of sleep or remain one long sleep. The baby sleeps at least 8 hours a night. Many children do not wake up leaving night rest uninterrupted.

11 Month Old Sleep

11 Month Old Sleep

Parents face a lot of challenges approaching the 1st year crisis and likely sleep regression. The schedule changes all the time. It is difficult to keep it within acceptable limits. The structure is affected by frequent overexcitation, and possible illness fears.

Do not seek to remove one of the periods of daytime sleep of the child to prolong the other. This may turn out to be the wrong decision, which will lead to severe overwork and lack of sleep. Try to build a schedule so that the time of leaving for the night is not too late. Vary your child’s nap time based on his wake-up time in the morning. Don’t give up on the routine.

11 Month Old Feeding

The diet of an 11-month-old baby should be rich in trace elements and vitamins. The basis of the menu is dairy-free cereals; fruit and vegetable purees; fermented milk products (yogurt, cottage cheese); meat purees (veal, chicken, turkey); dishes from low-fat varieties of fish (grated cutlets); breast milk or formula.

Do not forget about the presence in the diet of chicken or quail eggs, butter, and vegetable oils. Do not give your baby sweets, nuts, or fatty fish. Choose natural decoctions of dried fruits and non-acid fruits to drink. Sometimes you can give diluted juice without sugar. Most of the water should be clean drinking water.

The diet includes at least 5 meals. Breastfeed or formula feed in the morning and before bed. Use infrequent and only healthy snacks.

11 Month Old Baby Movements

Babies can take a couple of steps very well without support by the end of 11 months. Toddlers can pick up an object from the floor without squatting by bending down with their bodies. They sit down without support, deftly climb onto a sofa or bed and get off them.

More complex and coordinated hand movements appear: tweezers, manipulations with small details, holding an object for a long time. Movements become more coordinated, purposeful, and confident. Some children are already beginning to walk independently without support or holding one hand.

Movement skills are improved in regime processes: the baby takes a spoon and pulls it into his mouth. He picks up porridge or puree on his own. The child can drink from the cup by holding it with both hands.

Safety Around Child

The child is about 1 year old. He is now acting like never before. New physical skills are mastered and an attempt to walk appears. As soon as the baby wakes up, he immediately begins to move, crawl somewhere, climb, and walk. He is attracted by everything around him, but the child is not yet capable of assessing the danger.

The risk of injury increases with the advent of the first steps. The baby’s skeleton is still quite flexible and supple, but the possibility of injury is not excluded. The ability to stand up to their full height increases the risk that the baby will be able to reach the included stove, fire, sharp objects, or an open window.

Teething provokes the constant chewing of everything that falls into the hands. It’s not always safe. Any small object can get stuck in the airways.

2 Month Old Sleep

Stairs and stepsEven a small threshold of three steps can lead to injury to the neck or spine. The child is not able to calculate the risks of falling from a small height. Block access to stairs and small steps.

Furniture – Fragile and unstable furniture can tip over on the baby when he tries to climb on it. Remove handles from the chests of drawers and cabinets. Remove old furniture. Smooth out sharp corners at tables and bedside tables.

Kettle and hot drinksDo not leave a kettle of hot water on the edge of the table. Place a cup of coffee or tea away deep into the table so that the baby cannot reach it. A common injury in infants is burning.

Pantry – Keep your pantry locked. We often put unnecessary items, household chemicals, and electrical appliances in these places. A child can get into this room and get injured or chemically poisoned.

Windows and doorsBlock doors and windows with special protection. It will help keep your baby from suddenly closing the door or falling out of the window. Keep this situation under control and do not leave doors and windows open.

In a car seatNever put the car seat in the front seat. The car seat must be well fixed and the seat belts must be in good working order. Do not start a trip without checking if the child is fastened.

What To Schedule Next

Schedule a visit to the pediatrician in advance with the examination of the baby, weighing him, and the necessary vaccinations. The 4th dose of PCV13 is administered at 12 months. The recommended vaccines are MMR, VAR, and 2nd dose of HepA.

Schedule a visit to the orthopedist if the baby has already started walking. He will evaluate the correct positioning of the legs, and their location and exclude possible pathologies.

Children from 1 year old can already be actively developed in group classes. Plan to attend the most relevant courses for mom and baby. Sign up for first aid courses for children at risk of choking, cardiac arrest, or injury. This will be helpful for both parents.

Parents Tips and Development Speed Up

Study information on the age characteristics of the development of the child. Use tips that will help harmonize the process of learning, mastering new skills, and developing speech. Do not neglect additional safety measures that can prevent consequences that are dangerous to health and life. Take advantage of some of the most relevant tips from us.

  • Choose the right shoesThe kid should have good shoes along with the first steps. Buy exclusively leather models with closed hard edges and arch supports. At first, it is better to wear shoes at home while the baby is practicing walking.
  • Don’t use a walkerThese devices artificially create a situation in which the baby stands and walks upright. The beginning of the first steps must come on its own. Walkers are dangerous because the child can be seriously injured when falling.
  • Don’t stop breastfeedingKeep breastfeeding if possible. This is important for the communication of the baby with the mother and the replenishment of trace elements. A small organism cannot fully eat without its mother’s milk or formula.

The formation of the child’s intellect, the expansion of his horizons, and the replenishment of new neural connections depend on the parents. The more attention you pay to your baby, the more actively and efficiently he will develop. Now there is a laying of all the knowledge that will be further used in life.

5 Development Speed Ups

  1. Variety of play activities – Use complex educational games, role-playing games, finger theater, and more.
  2. Freedom of choice and action – Ban only what is dangerous. Give your baby freedom of movement.
  3. Stimulate regime processes – Let the baby take a spoon or a toothbrush and try to use it.
  4. Develop the child physically – Go in for swimming, physical education, massage, and gymnastics.
  5. Socialization Take your child to children’s shows and playgrounds. Allow interaction with peers.

The kid needs the time of parents and a prosperous atmosphere in the family for proper and harmonious development. The child will never feel psychologically safe if there is tension in the relationship between the parents. Always work on yourself and choose the most correct path for the future of your family. Comfort, peace, and a good mood in the family are the key to the proper development of the child.
