It's been several months since he's done that. Nothing I could do would help him go back to sleep. I gave him a glass of milk, changed his pull-up, gave him some blueberries to eat in case he was hungry, laid beside him, and nothing was helping. Finally got him to sleep after 2 hours of being up, and then his big brother comes into my room at 7 this morning. 5 hours isn't good for me.
