Can you cut his nap back to no more than 2 hours even if it means waking him up.

I did move lunch back to 11:00 and serve only a drink of milk for snack just before 9 and then babies go for morning nap. I found when they woke up they were hungry and saves being in the kitchen so long since the others see the snack and want it too. So lunch is 10:45 - 11:30 and then we have our story time followed by everyone into beds for 12:15 and up by 2:45.
