DD is almost 4 and still wears a nappy at night and for poo’s. Over the past few weeks she has been trying to take her nappy off at night. We haven’t switched brands and the nappies we use are the same type we have used for years. At first I didn’t mind too much I would just change her into a fresh one but when I put her to bed I can see her trying to take it off on the monitor. We have reverted back to tab nappies which made it more difficult for her but now she knows how to get them off. She definitely needs the nappies as when she wakes up with a nappy still on they are very full.
