I agree with some of you on the whole amusement park/disneyland etc etc.
Maybe I'm being swayed but this could possibly be another circumstance in which they should be used.
These places are HUGE and when theres tons of people there (in the summer) it can be ridiculous. Some people are so inconsiderate of others and their families that they just cut right in front and families and friends get broken up. I can see where a harness would be a great idea so that something scary like that couldn't happen.
But a shopping mall (maybe find a baby sitter) or the grocery store. EHHH I don't agree with it. Maybe you could even shop online.
