I thought that the first smile that Noah gave me really got to me. But recently he started doing these laughs that come from deep in his throat. I cant explain how amazing this is, the pure sign and sound of happiness. I just have to join in and laugh with him. Recently he also started pulling away from my breast a lot during feeding time, just to stare at me, give me a huge smile, and then giggle and laugh. This is like WOW. Happiness in its purest sense.
