i've tried every brand of nappies going and always had a problem. i was using asda's for a long time as i found them the best until they started splitting and leaking gel all over the bed in the middle of the night.
i thought i'd have better luck with a big brand so bought pampers. first night last night and it split and leaked in the night. tonight dd has had it on 1 hour and the elastic has snapped round the legs 
has anyone had any luck with nappies for night time that can hold a lot of wee or do i just have to do a change every few hours in the night?
