Mine go down between 12:30-1 and stay on their beds till 3. At 3 I go in and open curtains, get up anyone that is awake, change diapers, put away beds. Anyone that isn't up by 3:30 I wake up. That way we can move on to snack and the rest of the day which in nice weather is to go outside till pick up time.

I will also wake up a child having a morning nap if the length is beginning to interfere with a proper afternoon nap which gradually moves t hem onto the one nap routine like the rest of the kids.
