I'm not saying people shouldn't wing it, but some people clearly think they (or other parents) can control more things than are practical or healthy. You should try to be a responsible parent, but knowing how much you need to worry about individual things isn't easy. It's not practical to do everything various people say you should do. One expert will advise the opposite of what another does, and over times people flip flop back and forth. In the end I don't see how it couldn't involve some level of winging things.
