Luke is rolling over like Crazy.....

Well, at two weeks old, Luke rolled over about 5 times. On September 21 (little under 3.5 months) he rolled over again. On October 1, he is rolling over like crazy. He gets really upset though because he cannot roll back to his tummy yet. He grunts and squeals and gives up putting his head down and sucks his thumb. We get kind of nervous when he does this in the morning after waking up......oh the pleasures of a worrying mom and dad.
