Mama-rye- Congrats on getting a high needs baby! My DS1 was this way, and though he was a lot of work he is such a charming little firecracker. . . sigh. . . AP was tons of effort and emotionally and phsically exhausting, but WORTH EVERY MINUTE!!!! Hang in there momma! He'll be CEO of a fortune 500 company someday!
Diaps at night- well, I don't know if my boys have iron butts or what, but being pooped while they were BF never bothered them. Milo only grunts/fusses at night right before he poops- then he's happy. It really doesn't seem to bother him. And if I didn't have my lunablanket, I'd have to change him, although I should be able to find a CD combo that keeps him overnight. He's had no rashes, and my sheets are soaked in breastmilk by morning anyway, so a little nb pee is no big deal IMHO.

If he starts to get rashy, I'd have to change him too, but so far, no problem. Being fully awake to feed isn't an issue for us, either. He takes almost a full feed half asleep, so I don't have to make sure he's awake.
Also. the no stim at night thing isn't ignoring your BB at night- he sleeps in my armpit, so I couldn't exactly ignore him if I wanted to!

It's just- once you can get to this point, and it's easier the second time around- you just don't do anything you don't have to do. No lights, no burping (unless they need to of course) no changes unless necessary, low low voices, etc. It really does help them learn the difference between day and night. I still respond immediately when he wants to nurse, and if he fusses, and I don't know what's wrong, I'll definately turn on the lamp to see what's what, but only if we need to.
Plus- if you've got a 2 yo light sleeper in the next room, you avoid all crying that you can!
