Rolling over!

The last couple of weeks, when we put Porter on his tummy, he has been rolling right over onto his back. But, of course, I never have my camera ready because I think it's just a one time thing. Well, last night he did it again but this time I was prepared and caught the action! I put him back on his tummy after the 1st time and he rolled over again! Then, about 10 minutes later Sam put him on his tummy and he rolled over another 2 times. He doesn't like being on his tummy, he gets very irritated after too long.
Anyway, had to post another picture and I posted the video below this post. Enjoy!
