Is there such a thing as an 8 and 1/2 wakeful period??? DS has been napping like a champ for the last 2 months (wake at 7, nap 9-10:30, 12:30 to 1:30, and then 4 to 4:30/5 ish, bed at 7:30), he sometimes gets up once in the motn, but sometimes will sttn. Well the last 3 days he has hardly napped at all! He's so tired but as soon as his head hits the sheets, he's up screaming to get out of his crib. I left him home with DH yesterday to run some errands and DH said that he didn't take his normal nap, was up almost the whole time until he got so tired he literally collapsed in DHs arms and was out cold. Anyone else dealing with this?
