Blame Drystan! She was all like SPINACH SPINACH OLOLOL SPINACH EAT SPINACH.
Naran! Again! I'm not a female! XD
Ps. Obviously kids (from newborn to todler to before teens,) don't want your time 24/7. They still have to sleep. But if newborn/babies wake up during the night, they begin crying. If you (usually a mother,) walks around a corner, the kid realises the mother is gone, and starts making a noise. And if you don't pick it up, it'll cry more. So you give it something to occupy it with, and it's happy. For a few minutes before it wants attention again. My point was that a parent cannot just walk away from babies. They shouldn't be left alone, and you have to be there for them.
You don't give them attention straight away, so that they learn to resettle themselves (especially with sleep,) but you have to be there for them, just incase something does happen - and kids find dangers all over the house. You can't go shopping without leaving someone responsible with them. Or taking them with you, which can be a hastle in itself.
Then they turn into teenagers, where they don't want anything to do with you as a parent, but that's when you have to be concerned for them the most.
And when I don't have a lot of time (when I'm working,) to do too much with myself, and I add a kid to that mix which I'll have to spend time with until it goes to school, and then sort out how to get it to school and back, while working a full time job. Yeah... Not going to happen. And as to having the partner who does much of that, everyone is different, but if that were the case, I'd still have to spend most of the time with the partner (who's already worn out from the day with the kid,) and the kid, when I'm already worn out from work. It just puts a lot of stress and weariness on one, or both generally, parents, and I personally just don't want to put that stress on myself or the other person.
It's may be self-centered, but it's also realising that I don't have the time/energy/commitment to spend on a developing being, so I don't want to bring it into a life where it wouldn't get the effort. Kids just aren't for me. I like playing with them (cousins,) but I get to give them back, go home, and then work on my things. In that instance, I'm out of clothing, as I haven't had much chance to do washing in two weeks... (Been out regularly, and now the weather is cold and wet and washing isn't drying.) I'm not sure what I'll wear tomorrow.
Throw in kids, and what the kid'll wear, and the added clothing, and... Yadayada yada.
And as to eating your own poop... I guess you could - a little bit, not entirely. Dogs do sometimes. I wouldn't recommend a diet based on it though.
