We recently started chatting about children in the office -- we only have a couple of people in our team that have kids, although a few recent marriages probably means more are on the way. Great, just what the world needs.
I'm personally torn on the topic -- I think kids are cute and lovely, but only as long as they do what they're told and don't cry or throw tantrums or require any extra effort other than playing with them for my own personal entertainment and giving them back to someone when I'm done.
Not only that, but I find a crying child completely unacceptable in public. I recently sat on a 5 hour flight listening to someone's brat scream the whole time and by the time the plane touched down I was possibly a few seconds away from lecturing the parents on how they could have left the baby behind for this trip and just brought some photos along instead. Likewise, I think young children in restaurants is just rude, and I believe it should be understood that if you choose to get knocked up and pop these suckers out, then you have just chosen to confine yourself to private houses until your child knows how to act in public. It's only fair to the rest of us.
In the end, if children of any age refuse to act appropriately, I stand by the school of thought that says it's acceptable to use statements like "Hey kiddo, why don't you go play with the pretty bottles under the sink and I'll come see how you're doing in a couple of hours". Consider it a sort of Darwinian situation, with the end result being win-win for society as a whole.
