My boy didn't go without night feedings until he was 12 months. We didn't change his diapers at night though--just put an overnight diaper on him and changed him first thing in the morning. Unless they have a bowel movement, I dont' think there is a need to change them at night, it just wakes them up more. Its very very common for infants to wake up once a night for a feed until their first birthday--sounds like he's doing great!
