I'm in Australia and just wondering what the best night time nappies for a girl toddler 15 months might be? She's 11kg and just started wetting through at night. We moved her up a nappy size and she still overflows it! I think it's because she goes to sleep with a full belly and then her tummy deflates over the night, making the nappy loose? Not sure though. It's summer here so she's drinking a lot of water all day.
Any tips would be greatly appreciated!
