DD (2.7) has been potty trained for 5 months but still wearing nappies at night. These were very wet but a couple of weeks ago she developed a nasty cough which meant she kept bringing up her milk (which she has from an easiflow cup in bed)so we stopped giving her milk and now her nappies are usually dry in the morning. She still asks for her milk but I guess its better for her teeth not to have it last thing at night and she just takes a little longer to go to sleep. She keeps asking not to have a nappy on at night - she deosn't like them. I've just got waterproof mattress covers - should I go for it or is it better to wait until she's older and her nappies are always dry? she does ask me to take her for a wee and take her nappy off in the night if she stirs, but does still wee in her night nappy sometimes.
