I have dated a girl with one child, she was 24 I believe, and I was 30. Basically I was interested in sex and we had it twice in my car, thus the name backseatjuan. After she understood I'm not interested in an LTR with her, we never met again. Obviously these women are interested in an LTR, and they are choosing for themselves as well as for their child. Later, much much later, I found out she was dating another dude at the same time she was dating me.
Actually that girl was a pretty good choice, except for the child. She had her own condo, and her parents had a house. Good inheritance. Though back then I was only interested in sex.
Now that I'm well sexed and prefer a nice porno and some time alone to a nice piece of ass - I know - I'd stick with a girl that has no more than 1 child and her own condo and a house. I'd take half of that. No more than 1 child because she'd still could have two of my children.
Basically it's a common sense, if a girl has 2 or 3 children then there is no room for your future children. 1 child is fine.
These women devote most of their time to their children, so you're on 2nd place. Don't call too often, and be ready to make a lot of compromises because she would not be ready to go on a date with you when you want it.
