How long does your baby play? And what do you do to play with your baby? Just wondering...I have a 6 week old and he coos a lot, smiles, mimics and squeaks but for play time we have been trying to get him to do tummy time and he just doesn't like it. He barely tolerates it for more than a couple of minutes but he loves to play by talking and smiling at mom and dad. He can often play for 15 min or more. Just wondering what everyone else does for play time and how long they play?
