Could Regular Naps Be History?

For the last couple of weeks, Christopher has refused to take a nap while at home. I make him at least attempt to rest, but all he'll do is talk to himself, play in his bed and get up 1-2x for various reasons (usually to poop, of course). He still continues to nap *on occasion* at school (only when classmates aren't disturbing him), so I'm hopeful that the naps aren't gone for good yet!

Before the last couple of weeks, if he missed his nap, it wasn't *too* big of a deal (mainly just a torturous afternoon/evening); we'd just try to put him to bed early. He never used to have any residual effects the next day in his sleep routine or his behavior. However, there have now been 3 days when he's gotten up much earlier than normal after going to bed early the night before. I'm really hoping this is just a transition period, because he should be getting MORE sleep at night instead of the same or less!!!

I realize that he's of the age where naps may becoming few and far between, but I can still hope!
