Yep, as responsible parents we all do what we feel is best for our particular kiddo and family dynamic.
It's the parents that don't seem to give a hoot about others around them in a public place that get me. They either seem to be too lazy to handle the situation, or just don't care. Why did you bother starting a family in the first place, then...?!
We just got back from my folks a little while ago (DWifey, myself, all 3 kiddos, and SonIL were there - and, yes, we were solving all the problems of the world

), and this was part of the discussion.
It doesn't matter how inconvenienced you are, you chose to start a family, so take the time to raise it up properly. It's not rocket science.
