Growing and Changing

At just 1 month, your baby has already grown in many ways. He may have settled into a pattern of waking, sleeping, playing and fussing each day, and he may be more awake during the day than at night.

Perhaps the most satisfying development to take place in the fifth or sixth week of your baby’s life is his first smile. Have you noticed him smiling in his sleep? Soon, you will enjoy his first true smile in response to your face, your smile and your voice. He may even giggle.

These early moments of joy are a rich reward for the challenging first few weeks of parenting a newborn.

Your Baby’s Newfound Muscle Control

Your baby gains better control of his arms and legs by the end of the first month. Shakes and quivers give way to smoother movements. Watch to see if your baby moves his arms and legs rhythmically in response to your voice or in crawling motions if you lay him on his stomach.

He has more control over his head as his neck muscles strengthen and can turn from side to side. His head is still too heavy for his neck when sitting up, however, and needs to be supported.
