Evan started waving today. He's been making the actual motion for a while, but usu when he was excited about something. Today, every time we waved at him, he waved back - it's the cutest thing! I don't know if he's associated it with hello and goodbye, but I'll take it. I can't believe how much of a trooper he's been through this diarrhea ordeal, he's been so happy these last couple days. We started him on the special formula tonight and used the AF cream...hopefully this helps!
