You can start it now I think. Lay on your back and lay your son on his tummy on your chest. This is the best way to do it because he's more likely to stay there. In about a week or so you can put him propped on a pillow or with a rolled up blanket/towel under his arms on the floor. He'll only stay for about 10 - 15 seconds at first. Make sure to cover him with a blanket because it couldn't be drafty on the floor.
