Here is Blake's journey over the last few months of rolling over:
Now, he rolls over every time I put him down. It's a bit out of control, to the point where each time I lay him on his back for a nap, two seconds later he is on his tummy. Then he gets mad because apparently he forgot how to roll over onto his back, and he does not last for too long on his tummy. We are still so proud of our little roller.
