how does everyone get their baby to nap longer. my 4 month old used to sleep3-4 hours then another shorter nap during the day but that was on his belly. he don't sleep on his belly anymore and it seems he only cat naps during the day. Maybe only an hr tops but usually 30 mins or so. I can barley get him to make it til 7 and he used to go to bed at 8 or so. He usually takes a cat nap every couple hours or he gets cranky but I feel of I can get his nap to last longer maybe he won't be so tired.
