I dunno about that. I have a 2.5 year old and a 1-week old. And they're pains in the ass frankly. (Yeah yeah I love em blah blah blah). But young children are really hard to deal with. It's definitely a job for young adults, because I can't imagine grandparents having to raise toddlers - which some are forced to.
I'm ready for my 2 little boys to be....boys. So they can actually talk and go to games with me and go golfing. I think the young years suck so far. (But but you'll miss it someday! I don't think so)
