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.
