The 2 1/2-3 year sleep regression

Can we just talk about this sleep regression?

I talk a lot here about the 4-month sleep regression (when you feel bewildered and bleak), the 8-9-month sleep regression (when you feel defeated and hopeless), and the 18-month sleep regression (when you feel insulted and irate). But I haven't talked much about the 3-year sleep regression. We're in the middle of it here (although he won't be 3 until May), so i thought maybe some of you would like to complain along with me.

The other sleep regressions seem to be characterized by frequent wakings throughout the night, but this 3-year one seems to be all about not going to sleep at bedtime. When he first goes into his bed at 8, and is still awake at 9:45, it starts to piss me off. There's only so much water a kid can drink, the monster-scarer is in full effect, the temperature is fine, and no you cannot come out and read with me. And, what's more, your brother needs to stay asleep so he won't be tired for school tomorrow.

Honestly, at this point I don't even care if the little one actually goes to sleep, I just want him to be quiet so he won't wake up his brother. (The progressive lowering of standards also seems to be characteristic of the 3-year sleep regression.)

What I've finally come to is that I can provide him the opportunity to sleep, but cannot make him do it. We have a temporary peace with his staying in his bed quietly (so he doesn't wake his brother) and my not caring if he's asleep or not. I definitely don't think it's something he's doing on purpose. I think it's the same thing that happens at the other sleep regressions--the kids are working on something mentally or developmentally, and their bodies and minds just simply can't sleep right then.

This too shall pass.

Anyone else want to complain about the 3-year sleep regression? (And, moms of older kids, is there one coming at 6 years?)
