Long, Lean, and Strong

We learned at yesterday's one month check-up that Ty is in the 95th percentile for length and 25-50th for weight. He's 23 inches long and 9lb, 2oz at one month. The pediatrician said most babies don't like "tummy time" but Ty doesn't seem to mind. As soon as we put him on his tummy his legs get going and he scoots around clockwise. He'll pick his head up then put it down to rest. Last night he even flipped from his stomach to his back three times! The books/articles I have read say this usually happens at 2-3 months. By the way, the first picture makes his head look out of proportion with his body... it was the angle... the other three pics are more accurate!
