Sorry Mom that it's been over a week since I posted :)
This is the coolest thing Caleb does. We will point out face parts to him and when we get to tongue and stick ours out, he will copy us. He did it multiple times in a row so we know it's not a fluke.
I was so happy to discover that I wasn't the only one to like these lambs I made. Ever since he was just a few days old he always looks at the lamb on the wall while he's getting his diaper changed. It really calms him down actually.
