Now, I've been playing this game for a (quite a) few hours, and I've noticed something about breeding. If the breeding is going to be successful, right after the "kiss" and when they say "going indoors" if you click on their detail, the woman's will say "nursing" even if she hasn't made it indoors yet!
Of course, this is probably a bug. But it makes it easy to tell if the breeding worked or not, and if you're desperate for babies, if her detail doesn't say "nursing" right away, you can drag her back on her man and try for it again right away, rather than waiting for them to slowly walk indoors and then reappear empty-handed.
