Have just bought 2 bath seats for my 9 month old twins - until now we've been bathing them one at a time. I'm just wondering how you do it without leaving one alone in the bath, even for a few seconds, while you take the other one out?? Our bathroom is too small to get them both changed in there. Any tips would be helpful - would be great to bath them both at the same time, more fun for them and less backbreaking for me... I'm hoping!
