Your Baby... You Can...
…is getting stronger and may begin to move across surfaces by scooting or rolling.Do exercises together every day. Try pulling him gently up to a sitting position. To encourage him to roll to his tummy, lay him on his back and sit behind his head. Hold a toy that squeaks or rattles where he can see it. Slowly move it, so baby has to turn his head to follow it. Gently push his bottom to help him flip over if he needs it. Offer lots of praise.
…is trying to learn to talk.Talk to your baby about everything you do, even if you feel silly at first. Wait for him to answer and praise any sound he makes. Use simple words to describe what you do, so he can learn to associate words with events. For example, when lifting him, say “up.” While dressing, say “shoe.”
…may cry when he sees strangers and smile at voices and faces he knows.Make regular play dates with other parents and babies. This will help him get used to new people, while you’re there to help him. This will also help you find friends and possible caregivers when you have errands to run or you need some time alone.
…wants to watch, listen, touch and taste everything.Offer toys to stimulate the senses, with colors, texture, sounds and smells. Blow soap bubbles that he can follow with his eyes. Hang toys within reach of his chair so he can practice grabbing and letting go.
…loves to be near you and hear your voice.Read--yes, read--to your baby. Choose books with bright pictures and simple texts. Babies especially enjoy books with rhythm and rhyme. Don’t worry about reading from cover to cover. Read only as long as he seems interested.
