It's just one of those things that's really hard to know before you DO it, and then, well, there you are. I get why it is a challenging decision.

I actually wish I had a ton more kids. I really like them as people, and I say that as a total introvert who doesn't much like people. Although there's definitely days you WON'T like them. If you do do it, get a good babysitter you can trust and commit some resources to paying someone else to looking after them periodically when you just need a little breathing room.
