DS was 4 a few months ago. He's fully toilet trained during the day, and sleeps through from about 7.30pm until about 7am.
He still wears a nappy at night and it's always full in the morning (wet only).
I know it's largely hormonal, but is there anything I can or should be doing to help him get dry at night? I try not to give him too much to drink just before bed.
