1 Month Old Baby: Development, Sleep and Milestones

The growth and development of a child do not stop from the moment of birth. The kid gradually adapts to the outside world, his digestion is getting better, and communication skills and emotions appear. All achievements of the baby correspond to a certain age. The baby makes incredible developmental progress by 12 months.

Knowing the average parameters that your baby should have is important to control his proper development. Mastering new skills, both physical and mental, fit into certain age limits. Minor deviations from standard norms are not critical. We will consider the main features of growth, development, care, and safety for a baby at the age of 1 month in this article.

1 Month Baby Development

The baby faces harsh and aggressive environmental conditions immediately after birth. He will have to go through a period of adaptation which is different for everyone. Sleep and nutrition should improve, and heat transfer should be regulated. This is not an easy process for a young body. The newborn is still very weak at 1 month. He is capable of limited independence and sleeps most of the time.

Baby parts development summary

The most mature at the time of birth is the cardiovascular system. It is laid as early as the 3rd week of pregnancy. The placental circulatory system ceases after birth and cord clamping. The peripheral resistance of the vascular bed increases. The oval window between the atria gradually closes.

Newborns are characterized by a small bend of the ribs and a weak development of the intercostal muscles. Diaphragmatic type of breathing prevails. The gastrointestinal tract of a 1-month-old baby is adapted to receive only mother’s milk. It is characterized by functional immaturity. The maturation of the intestines is uneven. There is a high chance of colic.

Bones of the skullUnossified parts of the skull bones are present in the first month. They consist of remnants of the membranous skeleton and connect the main bones of the skull. Bone deformity caused by natural childbirth gradually disappears.

BrainThe average brain mass in newborn boys is 0.86 lb and 0.7 lb in newborn girls. The differentiation of the cerebral cortex is not completed. Vital regulatory centers receive the earliest development. Respiratory, vasomotor, food and excretory centers have already been formed.

Heart and circulatory systemThere is a restructuring of the physiology of blood circulation. Increases blood pressure. The foramen ovale is open. Heart rate 140 beats per minute. High coefficient of capillary filtration. A relatively large volume of plasma remains.

Respiratory systemThe respiratory cycle is gradually regulated. The respiratory sections of the lungs are represented by alveolar ducts and sacs. The surfactant-alveolar complex is mature. The pulmonary muscles are strengthened. Respiratory movements in mature full-term children are frequent and superficial.

Digestive systemThe capacity of the oral cavity at 1 month is still small. The volume of the stomach is also very small. Its digestion capacity is low. There is a lack of enzymes: amylase, maltase, and mucin. The structures and functions of the digestive glands are morphologically imperfect, and salivation is limited.

Kidneys and urinary tractThe first urination occurs within 24-48 hours after birth. The kidneys are well lobed. Functional immaturity of the nephron is manifested by a reduced ability to reabsorb water in the first months of life.

Your Baby Growth at 1 month

There are basic and most important parameters that are measured in a child from birth to 12 months. They are body weight, body length, head circumference, and chest circumference. The head circumference of girls at the age of one month is 37 cm. This figure for boys is 38.2 cm. The circumference of the chest of girls is 35 cm and for boys – 36 cm.

1 Month Old Baby Milestones

The period of postnatal development begins after intrauterine. It differs significantly in the strong influence of the external environment, its instability, and aggressiveness. A child is considered a newborn until 28 days after leaving the mother’s womb.

Each month of a new life is distinguished by its key points of development. The child will learn new skills, physical skills, and communicative achievements by age periodization. The main task of a newborn in the first month of life is to establish the vital functions of his body: digestion, heat exchange, and respiration. It is important to establish contact between mother and child.

Visual and auditory reactions A 1-month-old baby can briefly fix his gaze on bright objects. Eye movement becomes more ordered and smooth towards the end of the first month of life.

The baby can respond to sharp and loud sounds from the middle of the second week of life. The reaction is manifested by startling, awakening from sleep and blinking. Hearing improves gradually, capturing sounds of different tonality and vibrations.

Motor moments of development Smoothly moves legs and arms. The hands are often clenched into fists. Hands are either spread out to the sides or pressed to the chest. It depends on the tone of the muscles. The legs are often drawn up to the chest. Especially if there are problems with bowel movements and colic.

The newborn tries to keep his head slightly raised from the surface when laying on his stomach. He can fix this position for no more than 5 seconds.

Reflexes Innate reflexes are still strong in the first month of life. They help the child to successfully adapt to the environment. Basic reflexes: grasping (squeezes your finger), sucking (sucks the breast), search (looks for the breast), Mohr reflex (brings and spreads the arms to the sides), etc.

These reflexes will gradually fade away, giving way to the basic ones. It seems to mothers that the child smiles at them from birth, although this is a reflex facial expression.

Touch This is one of the main types of feelings. Skin contact is essential for a newborn to survive the birth crisis. The child calms down from touching the mother’s body. Tactility is necessary for a properly formed contact between matter and child.

The sense of touch in the first month is enhanced by breastfeeding. It is better to practice body-to-body contact with the baby if for some reason it is not possible to breastfeed.

Smell The child is sensitive to smells from birth. He perfectly recognizes the mother’s scent. The newborn smells breast milk and the mother’s skin. The child can respond if someone else picks him up.

The need for a mother is vital to him. The mother should be constantly next to the baby in the first 6-8 months. This lays the foundation for a child’s psycho-emotional well-being through smell and touch.

Emotions and communication The child is not yet able to communicate at 1 month. All the mother’s communication with him comes down to reacting to irritants with a cry. The irritants are hunger, cold, heat, and pain. The child screams if any of this is broken.

Emotions will become more conscious by the beginning of the second month, but for now, they do not work in the way we are used to.

The first month of the postnatal period is of little surprise. It is based on the reflex-adaptive functioning of the body. Brain development is proceeding at an intensive pace, but noticeable progress will be only after 2-4 months of development. We observe only an intense struggle for life, completely immersed in the satisfaction of basic needs.

It is very important to start introducing the regimen at 1 month and apply the baby to the breast more often. This will improve digestion and accelerate its development.

“Don’t try to compare your baby’s developmental milestones to someone else’s. Each person from the moment of birth is already on his life path.”

1 Month Old Baby Health

B right at the maternity hospital. It is given to most babies within the first 24 hours after birth. The second dose for hepatitis B is given at 1 to 2 months of age. Be careful with your umbilical cord. It should be completely healed by the end of 1 month. Most doctors do not recommend treating this place in any way if suppuration and poor regeneration are not observed.

A 1-month-old baby has weak immunity. Guest visits should only be in protective masks. Herpes viruses, cytomegalovirus, and covid 19 are dangerous. Wipe the skin of a newborn in vulnerable places daily: behind the ears, between the fingers, and in the folds of the skin. Put your baby to sleep with their head on their side and change sides for the next nap.

Sleeping Schedules at 1 Month

The baby is not yet able to navigate the time of day at the beginning of his extrauterine life. Enter the mode immediately, but until it is stable. Be patient and by 3 months the baby’s sleep will improve completely. The child’s biorhythms will be balanced and he will begin to sleep according to the regimen.

Match your baby’s rhythms to your family’s acceptable sleep patterns. Maintain daily sleep rates of 15 to 18 hours a day.

Daytime sleep can be divided into 4 naps of 2 hours. Night sleep in total should be at least 9-10 hours. The baby may wake up frequently at night to feed during the first month. The number of awakenings will be from 3 to 5 times.

1 Month Old Sleep

1 Month Old Sleep

Try to initially form a positive reaction in the child to sleep. Use sleep preparation techniques with pleasant rituals: bathing, massage, feeding, and sleeping. Repeat these steps before bedtime. Do not allow a negative attitude to lay. Keep silence, peace, and subdued light.

Healthy and sound sleep is extremely important for the good development of the baby. Sleep disturbances at such an early age can be the result of malnutrition, serious illness, or poor care. The sooner you can enter the mode, the easier it will be for you with the child in the future.

1 Month Old Feeding

A child at 1 month can absorb only mother’s milk and a specially adapted mixture. It is administered in case of emergency. For example, with severe underweight, little or no milk from the mother, milk intolerance, or jaundice.

Most neonatologists recommend feeding the baby on demand for the first month. You need to make sure that the baby is screaming from hunger and not from the discomfort of a wet diaper or pain. The child can hang on the chest for 40 minutes to 1.5 hours to establish the lactation process. Be more tolerant and further feedings will become shorter.

Long hanging on the chest is associated with the establishment of lactation and with the development of the baby’s digestive system. The volume of the stomach and the capacity of the oral cavity should increase.

1 Month Old Baby Movements

Conscious coordination of movements in a child only begins to develop after birth. In the first month, there will be no differentiated movements yet. Most of the activity is reflex. Newborns at this age often shudder, spreading their arms and legs to the sides. They squint and actively show facial expressions.

It is necessary to put the baby on the tummy from the first days of life. This should be done after sleep and before feeding and not after it. The tummy pose helps strengthen the back and neck muscles. The newborn will diligently try to hold the head.

All movements of the baby in the first month of life are slow and smooth. He will shake strongly, blush and squint only with strong crying and tantrums. The child actively works the jaws and the muscle around the mouth during feeding.

Safety Around Child

The human baby is the most vulnerable species on earth. He is not capable of independent existence at birth for a very long period. A newborn baby cannot survive without the help of adults. It is important to provide food and security. There are too many risks that can harm health and life.

Child safety

The most relevant safety for a child at 1 month is the prevention of sudden death of a newborn. Modern neonatologists recommend for this to put the baby to sleep on his back but with his head turned to the side. This position prevents the risk of sudden cardiac arrest and the possibility of choking when spitting up.

It is important to keep the newborn warm and not overheat. Control the temperature in the room depending on the season.

CribDo not cover the child with a blanket. The baby will not be able to remove it from the face in 1 month. There is a risk of suffocation. Try not to practice co-sleeping at this age. This could have tragic consequences.

BathroomUse baby bath pillows. Do not immerse it completely in water, just wipe and pour water over it. Never leave a child alone by the water.

StrollerMake sure your child is properly dressed for the walk. He should not be cold or hot. Check if the stroller is well ventilated. Do not use raincoats without ventilation windows and dense mosquito nets.

CarAlways transport your newborn in a special car seat. It must be appropriate for the age of the baby. The child rides head first according to the rules at 1 month. Avoid sudden braking. Never leave a baby in a car alone.

StreetAlways put the stroller on the brakes. Do not cross the street in the wrong place. Walk only on sidewalks and parks. Make sure there are no cars and that drivers can see you before entering the crosswalk.

FeedingNever leave your baby alone with food while formula feeding. Feed strictly by weight and make sure that there is no allergic reaction to the composition. Strictly adhere to the rules for sterilizing dishes.

What To Schedule Next

You must have a vaccination plan for this month of your baby’s life. Make an appointment for your second and third hepatitis B vaccine. Schedule a mandatory check-up with your pediatrician at the end of the month. They will have to weigh and measure the main growth parameters on it. The conclusion about how the baby grows and whether he has enough nutrition will be made based on them.

Be sure to check with an orthopedist by the end of the month. Early detection of hip dysplasia promotes rapid healing and recovery. It is recommended to undergo a course of professional massage and the necessary therapy if a problem is identified.

Parent’s Tips and Development Speed Up

Do not use unverified sources of information or advice from grandmothers and mothers. Ask neonatologists and other narrow specialists for help with your questions. Any careless manipulations with a child can adversely affect his state of health. Remain calm in any situation.

  • Day and nightTeach your child to tell the time of day. Then it will be extremely difficult to change it if the child confuses them. Close the curtains and create silence in the evening. Use the same rituals before going to sleep at night.
  • Techniques for colicLearn first aid techniques for colic attacks in a child. Practice belly massage, belly down soothing poses, and rocking. Extreme measures are the use of simethicone and dimethicone to pass gases.
  • Monitor your child’s urinationThe baby should urinate after almost every feed. He may not be eating enough. Perhaps you are not getting enough milk or he is suckling at the breast for nothing, not being able to squeeze out the milk.

Remember that a child is a socially oriented being. The atmosphere in the family and the emotional state of the mother are directly reflected in his development. It depends only on you how correctly and quickly the baby will grow and develop. Begin to engage in its development immediately after birth.

5 Ways to Speed up Development

  1. Laying out on the stomach Always lay the baby on the stomach. Do this after every awakening.
  2. Communication Communicate with your child verbally. This strengthens the connection and helps trigger speech.
  3. Show items Use bright pictures, toys, and balls. They should attract the attention of the baby.
  4. Give items in hand Develop your child’s motor skills. Give him objects of different textures.
  5. Turn on music and sounds of nature Put light classical music, the sound of the sea or rain in the background.

Your child’s life depends entirely on you. Everything that is invested in his development from an early age will reflect on his later ability to succeed in school, university, or college. The brain requires constant training from the first days of life. Try not to forget that meeting the basic needs of life is not the end of child care. We are social beings and an integral part of our development is communication.
