Here is what is going on with Noah this week according to babycenter.com;
When placed on her stomach, your baby will lift her head and shoulders high, using her arms for support. This mini push-up helps strengthen her muscles and gives her a better view of what's going on. She may even amaze you (and herself!) by rolling from her back to her front, or vice versa. You can encourage this skill through play: Wiggle a toy next to the side she customarily rolls to in case she's interested enough to try again. Applaud her efforts and smile. She may need your reassurance since her new skill can be frightening.
By now, your baby may respond to your presence, your voice, and even your facial expressions by kicking and waving her arms. Your baby, who up to this point probably smiled at everyone she met, is also beginning to be picky about the company she keeps. In large groups or with unfamiliar people, your baby may need time to get comfortable. Allow for transition time with strangers or when leaving her with a sitter. When she's safely in your arms, though, she's likely to be interested in interacting with other people — especially noisy, boisterous children because they're more active, more amusing to a baby, and physically less imposing.
Noah gets more and more fun each week. His personality continues to develop and he continues to become more interactive. He isn't showing any interest in rolling over yet. He is becoming a lot more talkative, and will go on for extended periods of time making fun noises at us. He loves holding his rattle and hearing the sounds that his crinkle toy makes when he grabs it. Most of the time when he fusses it seems that he's tired and goes right to sleep, but other than that he is a very happy, laid back baby. Noah does really well around other people, we usually have about 15-20 people at community group each week and the volume can get quite loud when we have several conversations going on at once. Noah seems to enjoy the social activity and stays happy as he is passed around from person to person.
Just for fun, here's a comparison of Noah in his bouncy chair at age 2 or 3 weeks (left) and him in his chair this week (right)... what a difference!!!!
