I think people who don't have kids need to ease up a little. How are children meant to learn how to behave somewhere if they are never allowed to go to the places in the first place. I take my daughter with me everywhere I can, she has a disability that looking at her no one would know and yes sometimes she plays up, if she starts I simply remove her from the situation and try again with her some other time. Having people tutting, giving dirty looks and presuming your a bad parents because your child misbehaves is not a nice feeling at all. If you don't like children go places where they are not allowed, but just remember to always look at the bigger picture as to why the child is misbehaving in the first place.
