Your Baby at 4 Months

Updated: Jan 19, 2021

How your baby plays, speaks, learns, and acts is important! Paying attention to these things helps us get a better understanding of his or her development. Although unmet milestones does not always mean trouble, understanding these typical developmental milestones will help you determine the need to speak with a pediatrician.

So, what can your baby do by 4 months old?


  • Smiles spontaneously at people

  • Likes to play with people and may cry when it stops

  • Copies some movements and facial expressions, like smiling or frowning


  • Begins to babble

  • Babbles with expression and copies sounds

  • Cries in different ways to express hunger, pain, or being tired


  • Lets you know if happy or sad

  • Reaches for toy with one hand

  • Being to see hand/eye coordination, like reaching for things

  • Follows moving things with eyes from side to side (called tracking)

  • Recognizes familiar people from a distance


  • Holds head steady, unsupported

  • Pushes down on legs when feet are on a hard surface

  • May be able to roll over from tummy to back

  • Can hold a toy and shake it, or swing at dangling toys

  • Brings hands to mouth

  • Pushes up to elbows when lying on stomach

How can I help develop my 4 month old?

  • Set steady routines for sleeping and feeding

  • Copy your babys sounds

  • Pay close attention to likes and dislikes

  • Act excited and smile when your baby makes sounds

  • Have quiet play times when you read or sing to baby

  • Give age-appropriate toys, such as rattles or colorful pictures

  • Play peek-a-boo

  • Provide safe opportunities for your baby to reach for toys

  • Put toys or rattles in your babys hand and help him hold it

  • Hold your baby upright and sing or talk while baby attempts to “stand” with support

If you are concerned about any of these things, ask your pediatrician for guidance. Check out our other article about milestones and parenting.
