Our two-year-old will stay up. He may not make it through the whole party, but he can stay up late! We have two over 18 kids and they were never able to stay up at age 2, but this one is different. If we do MVMCP, I'm planning on putting him down for a late nap. Every time I put him down past 2 or 3 at home, he ends up not wanting to sleep at his usual bedtime of 9:00 to 9:30. I've noticed that he will stay awake for at least seven hours after waking or after a nap, so I figure if I put him down a little later, say 3:00 and he sleeps for an hour and a half, he will make it through the party. He's not real into princesses, but he does talk about the castle a lot. Maybe we will hold off on that until later. Is Askershus a castle, too?
