For ds 15 months all every two hours we change with bbh hemp or bambo, we use 1 or 2 pull covers daily and at night 1 bbh magical all in one.

when we use bbh magicals during the day we dont need pull covers or nay cover as it is a all in one we use about 5 or 6 daily they can last up to 6 hours we have pushed them to 12 hours over night.

hope this helps.
