My DS is 3 and a half, 4 in October, he's been dry during the day for about a year but wears a nappy at night.
When he wakes up in the morning he's usually got a very wet nappy. (still has a cup of milk/water before bedtime - refuses to go to sleep without it)
The main problem is he saves up his poo and does it either as soon as we put his nappy on at night or first thing when he wakes up in the morning.
Any ideas on this?
