Yup. One can always learn from others.
Newborn/Infant. Unable to talk, may or may not be crawling at this point, or has maybe even taken his first step, but unable to care for oneself even rudimentarily like a toddler can. Well within the debunked tender years doctrine. If you want to draw a big dividing line, that's fine. Point being, very very young.
And as Ohiogal says, we beat others up when they take a me-first attitude. OP in the other forum took a bit of a beating for putting himself first, and throwing flimsy excuses out there, and arguments were debunked heavily and forcefully.
And she is right, we are not as much of a legal forum. We're more hands on than legal - concepts to ensure that the child's rights are protected, although I can see how one would think we're a bunch of lotharios... Well, we get dads, that's our focus. Although we will lead horses to water, we're not as well versed in the complete intricacies of the laws. Very highly educated, though, not in normal schooling ways like Ms (Mrs?) Ohio or debtcollector, though.
I took umbrage at the Fight Club comment, because it is not like that at all. We don't protect dads, we don't circle the wagons, we'll call out their behavior. You'll find a few 'mens rights' (whatever that means) types on that board, but most of the more senior members take a child's best interest standard, so what is best for the child is the correct and right thing to do. May we shade towards dads? Yeah, that's the purpose of the board. I haven't looked, but there are moms boards out there, too.
