Can anyone give me some advice on how to stop nappies leaking at night time? I have 4 month old son, and practically every nappy at night leaks (none in the day). I am checking that his willy is pointing down, am pulling out the frilly bits, doing them up very tightly, but still they leak. Have tried 4 different brands. Any advice welcome, as we are up 3 times in the night and I am sure he would be sleeping through much more if he wasn't getting wet. Thanks.
