DS is almost 2 and we are not planning on toilet training any time soon. He wears Pampers Baby Dry Extra Protection for overnights in size 6, the largest size. (Since he started sleeping through the night we have used this brand in 1 size larger than his daytime diapers, and have had great results). We have a few months before he outgrows them, but what comes next?!?!? They don't go up to size 7! What do you all recommend? Would prefer a disposable diaper (so, no insert) if at all possible.
