3-Month-Old Baby

What a charmer! By 3 months, baby is probably smiling plenty, and she's likely started to imitate what she hears and sees (so watch what you do, mama!). You should chat with her throughout the day, describing what you're doing, how you're doing it and where you're going -- this is how she'll eventually learn to talk! Just don't go too crazy. Baby is a quick learner, but she needs you to keep things clear and simple, and to recognize when she needs a break.

your baby is 3 months old!
  • She sleeps about 15 hours a day, maybe for a 5 or 6 hour stretch at night.
  • Feedings are probably about every three or four hours.
  • She's likely gained another 1.5 to 2 pounds and grown 1 to 1.5 inches. The size of her head may have gone up by a half inch, too.
  • She's mimicking some sounds, movements and expressions.
  • She's a creature of habit -- bedtime, nap and feeding routines keep her happy.
  • She's working at becoming a great communicator, making eye contact with you, and she can now recognize your face.
  • Let her play on the floor or under a baby gym, since she loves to kick up a storm and swing at things.
