Baby This Week: 3 Months Old

Your baby is probably able to sit upright when propped up by blankets or pillows. If she can do this for short periods without slumping forward or immediately toppling to the side, by all means let her enjoy the new views that come with sitting upright on the floor or next to you on the sofa.

Your baby has been able to recognize you since she was just a few days old, but now she may actually be able to show it. About half of babies this age begin to exhibit an obvious recognition of their parents.

Your baby will probably continue to smile at strangers, especially when they look her straight in the eye and coo or talk to her. But she's starting to sort out who's who in his life, and he definitely prefers you, your partner, and perhaps a few others.

Your baby may quiet down and make eye contact with you, or she may search for you in a room and move her arms in excitement or smile when she finds you. She may even find your scent calming and comforting.
