Toddler is around 16kg and we've been using Aldi and Asda nappies just fine, but I feel like they've changed recently, don't know if anyone else has noticed. Asda seemed to change the weight ranges of their sizes, and I'm not sure if Aldi did too.
Aldi ones now seem to leak all the time and I've worked out that it's because they are too narrow - they end up going up the bum so one bum cheek is hanging out! It's particularly bad at night because obviously I can't check the fit regularly and she keeps waking up soaking right through pjs and sheets. The nappy is sometimes not filled at all.
Does anyone have any recommendations for disposable nappies which are maybe a bit wider at the back?
