Sleep trouble

Lacey

For the last week my son hasn't been going to sleep until 10! His bed time has always been around 7:30 or 8. But now that he's staying up late he's too tired to wake up in the morning even though we have to be out of the door by 7a.m. and when I do get him up all hell breaks loose because he's too tired. Even daycare has noticed him acting different and cranky from lack of sleep.

He has a routine for bed so I don't know how else to correct this
