So recently DS who is 27 months and typically sleeps through the night 11 hours with a 1.5 hr nap during the day is fighting sleep hard!
He usually goes down without a fuss and wakes up happy. The past week he has been fighting with us about going to bed and crying for us to come back into the room. He has also been waking up super early crying for us saying "no go to bed". Typically I'd probably just let him CIO in the AM but since he's potty training as soon as I know he's awake I get him to go potty.
Any thoughts on what's going on? Or how to fix this?
And just for the record, he's not teething or sick.

Re: Sleeping Difficulties
Is it possible he's ready for a shorter nap? Or maybe needs a different bedtime?

It's possible he is starting the process of dropping his nap. DS naps at 1. We wake him up from his nap at 3:30 so he will go to bed by 7:30/8:00. So he still naps but not for as long. This is working for now anyway.
