Overnight diapers

Katie

What diapers do you guys use at night? My son sleeps 12 hours and we try not to change his diaper during the night because it wakes him up. He is 15 months olds. He was doing fine with Huggies overnight diapers and now he is peeing through the diaper. We tried a size up and it's not working . Unless he wakes up I dont want to have to wake him for a wet diaper. Suggestions?
