Brecken is starting to really interact with us. He smiles and coos often when we get close and talk to him. He has also started enjoying his playmat. I had him laying on it yesterday and he was kicking the toys vigorously with his feet, hitting them with his hand and licking one that was hanging near his face. He's also been sucking on his hands quite a bit. Still having trouble opening his hand enough to actually suck on his fingers but he sure does try!
