I don't have children myself but if I had I would certainly try and take them to shows with me - or, take them to shows they want to go to. Provided that it can be done in a sensible and safe way, of course. My parents weren't interested in music and hated to take me to shows (we lived in a really rural area so it was always quite the trip) - so I'd definitily love for my kids to be able to have that experince.
I have a friend in the UK who takes her 2 sons to alls orts of gigs - and they absolutely love it, have already met quite a few musicians and have started playing drums and guitar.

So much better than just computer games all day.
I have seen children at NMA gigs in Cologne, for the Christmas show - never an issue, everyone always tries their best to make sure they get to enjoy it.
