Congratulations! You made it past the first 3 months with your newborn. By now you should (hopefully) both be sleeping better and into a normal routine.

  • Grasping objects with both hands
  • Beginning to develop eye-hand coordination skills
  • Likes swinging, rocking, or being bounced

Other Things Your Baby May Be Doing

Some babies develop quicker than others and may possibly be showing some of the following skills:

  • Hold head level with body when pulled up to sitting
  • Sit up without support
  • Object to having a toy taken away
  • Turn in the direction of a particular voice (specifically mommy’s)
  • Bears partial weight on both legs when held upright

Your baby may also be ready to start solids, typically rice cereal. Refer to our guide on introducing solid foods under Baby Feeding to determine if your baby is ready to begin eating from a spoon.

4th Month Check-Up

Along with questions regarding your baby’s eating and sleeping habits as well as overall development, your doctor will perform an assessment at your child’s 4th month wellness check. All doctors and nurse-practitioners have different techniques for assessing patients, but this is generally what you can expect during your child’s physical exam:

  • Baby’s measurements: weight, length and head circumference
  • Vitals: temperature, chest sounds
  • Infant development 4 months assessment to check head control, hand use, interaction, etc
  • Guidance and recommendations regarding sleeping, feeding, along with infant safety
  • Second round of immunizations
  • Suggestions and recommendations on beginning your baby on solids

If you chose to have your child immunized these are the vaccinations generally given at 4 months.
DTap second dose – protects children against Diphtheria, Tetanus, and pertussis
Hib second dose – protects against the Haemophilus virus type B.
PCV second dose – wards of the pneumococcal disease.
Polio second dose – protects against the Polio disease
Rotavirus second dose – protects against the Rotavirus

Your doctor or nurse should give you instructions or papers regarding the shots and what reactions to look for as well as how to treat them. Your doctor may decide to put off certain vaccines due to a medical condition or if your child is ill.

Keep in mind that babies will develop at their own rate and may do some or even all of the above listed infant developmental 4 months skills. If you notice your baby hasn’t achieved any of these skills, consult with your doctor. It may be perfectly normal, though in some cases a delay in infant development could be an indication of  a medical problem.
