smiling baby?

So I figured that when Noah smiled at me on Monday that it was just a fluke, you know gas bubbles or something of that nature. Well last night Noah smiled at Grandma. Not just a little smile, but one that starts on the inside and comes out. It was so sweet and Grandma just about melted. So I'm guessing that Noah really did smile on Monday. It was right after he'd eaten and he had milk all over his chin. I laughed and asked him if his dinner was good and he smiled. Wow he's growing up so fast!!
