Big Man

When I first saw these photos, I thought 'He looks like a big boy- where did my baby go?!?' He sits up with a little assistance and just this morning I laid him on his back on my bed and 2 seconds later he was on his left side! I love to see his progress, but I know that soon he'll be running away from me in the store and yelling at me, 'NO, Mommy!' I am not ready for him to grow up! What's a mom to do?
