I just went back to work. LO will not sleep for OH or my parents when I am gone. I am gone about 9 hours and he is only sleeping about 2 thirty minute naps. When I am home with him he takes about 2 ninety minute naps and a 2 hour one. He naps just fine at my parents house when I am home too. Even with OH at home laying on my side of the bed with him doing the normal routine, he sleeps for 20 minutes and wakes up screaming. The other night I came home and he was so overtired, screaming, nursed, and then fell asleep for 9 hours (not that I am complaining about the sleep part!). What do you think??
