Rolling already!!!

I can't believe it. Shane called me yesturday at work to tell me that Levi had almost rolled over... Well today was the day. He rolled for the first time from tummy to back. After a couple of rolls he started spitting up so we stopped for a while. His tummy wasn't so sure about it. Sometimes he gets his arm stuck and he tries to roll and it hurts his arm so assistance is needed every once in awhile.
