Posting from the US so 6 hours before time of post; not up in middle of the night ...
This thread seems to be unfairly harsh to Spidermama, with whom I agree on this: all parents should be aware of the needs of the majority. Perhaps that is too un-PC for everyone to swallow; whatever; it's true. Common manners dictates thinking of others, and if I noticed one "bad apple" ruining a situation for 29, I would conclude the fault certainly lay with her parents. And if I were her mother, I'd be outta there.
Don't honestly know what I would do if we had problems with our DS. Guaranteed I would be keeping the above in mind, though. We don't take 2.5 year old DS to movie theaters or fine restaurants because (barring a special kids' movie or special event) those aren't places for 2 year olds - I remember what it's like to be disrupted by someone else's child in those locations, and would be super
if mine were the problem! So we avoid that as parents; why wouldn't we?
While "unfair isolation" of a violent child is one take on it, perhaps the real story is the child's just not ready for certain situations yet, and until you can get to the source of his behavior, why subject others to it? We'll be taking DS to theaters and fine dining - when he's 6, or shows he can handle it!
So kudos to you Spidermama; you're every bit as courageous as Flip for posting what you have on this very interesting thread. Sympathize with you too, Flip; don't think I don't. No one should have to deal with what your child puts you through.
For what it's worth, I've never once encountered a consistently violent child in my short 2.5-year career as DS's parent here in US. I consider myself lucky, esp. after reading this thread.
