I had the same feelings a couple weeks ago. I was worried that Ava hardly ever smiled or cooed or anything and everyone else was sharing pictures of their babies smiling at the camera and whatnot. But this past week or so she's all of a sudden been so smiley and she's starting to "talk" to us a lot now. Like Heather said, all babies develop a different paces, I'm sure Max will bust out with tons of smiles really soon!
