Watch Me Grow: Your Baby’s Development in Months 1 to 3

Babies develop quickly in the first three months. These milestones in social, language/cognitive, large motor, and small motor areas help you know if your baby is developing normally.In their first three months, babies seem to change before our very eyes. One day they’re tiny, helpless newborns who sleep most of the time. Suddenly they’re holding their heads up and moving their arms and legs with delight.

How can you tell if your baby is developing normally? We know you’re busy (and maybe a little sleep-deprived?) so we’ve made you a quick summary of some key developmental milestones. Below those, you’ll find some helpful resources to answer further questions you may have.

Keep in mind that some babies might be “ahead” in one area, and “behind” in another. That’s perfectly normal, pediatricians tell us.

“Don’t look at the time as much as the progression, and see that your child is changing and growing. It’s not a race. Nobody’s going to ask on a college application when your child first walked or said ‘da-da.’”

-Jennifer Shu, MD, pediatrician and co-author of Heading Home with Your Newborn.[1]

Four Areas of Growth

Your baby develops in four general areas:

  • Social (interacting with people)
  • Language/Cognitive (communicating and thinking)
  • Large Motor Skills (moving the parts of his body)
  • Small Motor Skills (making subtle motions, like grasping objects).

Let’s look at some of the ways babies develop across these areas from birth to three months:

Babies develop in four areas: social, language/cognitive, large motor skills, and small motor skills. This inforgraphic lists a key developmental milestone in each area during baby's first three months.

How You Can Encourage Your Baby’s Development

To help your baby as he changes, you can:

  • Enjoy your baby: pay him lots of attention, learn his signals (“I’m hungry” or “Too much noise”), cuddle with him
  • Give him plenty of outdoor time, and time with people who enjoy him
  • Give him lots of eye contact as you sing, talk, and read to him
  • Give him tummy time: let him play on his tummy (while you supervise) and practice using his muscles
