Baby Feeding at Month 3

At three months,your baby is still taking breast milk or formula exclusively.  Your child will also feed less frequently but eat more at each feeding. A breastfeeding baby feeds 8 times a day and a formula-fed child eats every four (6 times) in 24 hours.

A breastfed baby suckles for at least 10 minutes with evident swallowing. The child should also seem satisfied when they stop feeding. Bottle-fed babies, on the other hand, consume 6-7 ounces at each feeding.

If you are unsure whether your baby is eating adequately, track their wet and dirty diapers. A well-feeding child will have approximately six wet diapers and one dirty diaper (or one every 24/48 hours)  every day.

Baby Sleep at the third month

Your three-month-old baby will sleep between 14 and 17 hours a day, including three to four naps of about 4-6 hours. 

At night, a 3-month baby can sleep six to eight hours. Your baby’s increased stomach capacity enables longer nighttime sleeping sessions because the child requires less night feeding.

While your baby ‘s sleeping routine is unpredictable, you may start noticing a few patterns;

  • The number of naps they take
  • How much  time they spend sleeping
  •  When they usually fall asleep and wake up

For safe and restful sleeping;

  • Always ensure that your baby sleeps in their back
  • Make sure your baby’s crib (or any sleeping surface) has a firm mattress and has well fitted bedding
  • Ensure your baby dresses well for the sleeping room temperature

Baby Development at Month 3

Your baby’s development at three months is happening drastically. Their sense development, strengthening of the brain memory pathways, maturation of the nervous system, and an increased range of emotions cause fast growth.

Below is a look at your baby’s physical development and movement, sensory growth, mental development, and social development of your three-month child.

Physical Development and movement

Your baby’s fontanelle, the soft area at the back of their head, should be closed by the third month. The soft spot at the top of a newborn baby’s head, however, will still be present. Also, your child’s head is still bigger than their body.

During the 3rd month, your baby begins to move around because of their increased muscle strength.

At three months, your baby can hold their head steady for longer when you hold them in a sitting position. Also, your baby can now lift their head and shoulders when lying on their belly. Your little one’s neck strength and head control increases following their upward and sideways looking movements when on their tummy. Other kids can extend their arms and their elbows for support as they explore their environments.

Your baby’s back muscles also start to strengthen, preparing their body to  finally sit straight unsupported, crawl, stand, and walk.

Your baby also becomes more aware of their hands and arms at this point. They spend much time looking at their hands, clasping them at their eye level, and trying to put them in their mouth. The baby’s hands also begin to uncurl from their usual clench fist position. Opening and closing them, and spreading them. Ultimately, your baby acquires enough hand and finger dexterity to pick and hold toys and light objects.

Your baby’s legs also become much stronger, enabling them to flex their knees and legs at will. The strong leg muscles also enable the child to kick hard enough that they flip over. Other babies also start rolling from their backs to their sides, and back to their backs.

Sensory Development


Your baby’s sight matures rapidly, developing convergence vision and divergence vision steadily.  Your baby’s maturing distant sight enables them to notice pattern details and the whether there are multiple objects. Your child’s interest  in primary colors also increases.

During this period, your baby also develops shared attention. Your baby can now look at your eyes and then look at what you are looking at, enhancing their social skills too. 


Your baby’s hearing sense continues to mature. Your baby may become quiet when they hear  your voice and become excited when they hear a favorite song or their siblings’ voice.

Signs that your 3-month old baby’s hearing development is includes;

  • Reacts to noise
  • Calms down when they hear your voice
  • Halts feeding when they hear noise
  • May talk back to you -cooing and gurgling
  • Looks at you when you talk or speak
Taste and Smell

By the end of month three, your baby begins to differentiate tastes. Your baby can distinguish between breastmilk and formula or different brands of formula.

Your baby will also prefer some smells to others. Different smells will affect your baby’s feeding, sleeping, and relaxing; the baby may have eating difficulties in the presence of smells they deem unpleasant.

Mental Development

Your baby’s brain now has greater control over its body because of its much-matured brain.

Your child’s memory also develops greatly at this age. Your baby can understand the connection between their actions and reactions; crying will get them their attention and smiling will get a smile from you.

Your baby’s mental maturity also multiplies their communication abilities, including sounds and gestures. Your child can now smile, coo, squeal, and gurgle.

Social Development

Your baby can now make and maintain eye contact with you. Your child may also giggle or laugh in response to touch, vocal, and facial expressions. 

Your baby will also now cry or become fussy to get your attention. Your responsiveness to their cries will help them develop trust and a sense of security in you.

Baby Hair on the 3rd Month

At three months, your baby could still be spotting bald spots from the continuing normal hair loss of an infant.

Other times, you may notice your baby’s hair shedding because shedding and hair growth can occur at the same time. The new hair, however, could be of a different color.

Your Baby’s Appearance at Month 3:

Your three month old baby continues to grow steadily. The baby gains between 1 and 1 ¾ lbs per month and adds ½ in the month. The child’s head circumference also increases by a ½ inch.

Approximately, a three-month old boy will  be about 24 inches and just over 14 lbs (6.37 kg). A three-month old girl measures 23 ½ inches (60 cm) in height and weighs about 12 lbs and 12 ounces (5.8 kgs).

Vaccinations on the third month

A three-month-old baby does not get vaccinations. From the 2 months shots, the next ones that your child will get will be in their 4th month.
