That is the bit thats scarier for us than them, i got it wrong on Chocko last night and was pottered by it but it didnt faze her, the problem is if we get it on and they panic its too late as its neither on nor easy to slide off, thats where it went wrong with Bella as she panicked, tried to escape and crash landed, however, Chocko and Danny boy are a bit different, if Chocko did start panicking i could just turn it into a tickly silly game and while she was distracted i could get it off, Danny boy sounds the same if you can spin him about and upside down. Try and be confident when you put it on and turn it into a game, easier said than done, i was shaking last night for worry she would get caught up in it, she did a little but it never worried her.
