I have a 10-mo. old who has been able to fall asleep on his own and sleep through the night for a long time. He recently has figured out how to stand up in his crib, and this went out the window. He won't go to sleep for his naps until he is exhausted, and ends up falling asleep crying because he is so tired, and instead of settling himself back to sleep when he wakes up during the night, he stands up and cries, and won't go back to sleep on his own. He is up about 5 times a night now. Anyone had this problem? What did you do? I have no ideas. Thanks
