That is sad about your family--the not getting along. I know that happens a lot, but sorry you have to deal with it too! The thing is that just because you are family doesn't mean everyone likes each other and will get along. Sometimes it works, and sometimes it doesn't.
I was thinking about how parenting used to be when I was growing up just the other day. My mom had it so easy. We would run around the neighborhood all day in the summer and she didn't have to do a darn thing (not that she wasn't attentive, but that is what we did back then) And then at home it would be my sisters playing with me. It was just so different and less interactive. Not that I don't like time with my child, but I do like the independence thing we had going on
And I agree about getting children used to being places. Our son has gone out to eat with us since he was in a carrier, and he has always been easy at restaurants so we could go pretty much anywhere. It does make it easier. And it is good to travel with them, as it gets everyone used to being away from home.
