I don't know when boys are suppose to stop using diapers a night. Matty's cousin stopped a long time ago, but some of his friends still use it. I guess it's different for each kid, and it depends on when they're ready.
It was last week when Matty was finally ready I guess. He woke up with a dry diaper in the morning, and was really happy. Matty quickly said he didn't need to wear it to sleep anymore. But I told him he can stop using it at night if he can have a dry diaper in the morning for 7 days in a row.
He sucessfully did it for 6 days .... but on the seventh day his diaper was wet again. I thought it was because I made him drink extra water for his cough the night before.
