PB - I do think you have been very lucky. Either that or you have more patience and fitness than I do. I can't keep up with the girls when they run off - even when I am well - and have been in the situation where they have run into carparks before so I much prefer prevention at the moment. If we lived in a different culture I would still be wearing them while they are in the running off stage, but I can't so I do what is the next best for them (Oh and they can get out of 5 point harnesses on the pram and car seat) and they get some exercise.

Exactly why I understand people using them. I would rather you got your 3 (soon!) girls home safe, then have something terrible happen.

Just as folks have the right to love them, folks also have the right to hate them!!!
