M.L.
can you try getting him up earlier in the morning instead of letting him sleep in? he might be crabby for awhile but that might get him to go to sleep earlier in the evening if he's tired. it'll only get worse as he gets older unfortunately. we had great success with the "timer". my son didn't want to go to bed at all and we started setting a timer and told him he could play or do whatever he wanted until the timer went off. when the timer went off he had to go to bed. Now he WANTS us to set the timer! Funny how that works. But instead of him going to bed at 10:30 ish every night, he's in by 9. it's still later than i would like, but it's better than 10:30 or 11!
