I'd really like to have a second kid, but, I'm having a hard time understanding how I'd survive it.

LO is 18 mos and does not sleep through the night. He's up at least 3x every night now. I'm just barely managing to get enough sleep to stay functional and sane enough to stay employed.

I can't imagine LO#1's overnight needs plus pregnancy insomnia or a newborn. There's also the bit where I would need to have sex regularly or at least occasionally to get pregnant in the first place. My sex life has been pretty badly damaged by having a kid who only sleeps in 35 minute to 2.5 hour chunks.

I'm sure his sleep will eventually improve. But, I'm 35 and my partner is 41; we can only wait so long.
