how many newborn diapers? ?

I'm going to have 2 under 2 and both in cloth. I'd like to wash every 2-3 or 3-4 days. I heard newborns can go though about 24 diapers a day..was this true for you? how many newborn diapers would you suggest so I'm not washing diapers everyday on top of all the baby and toddler clothing. I'll be using mostly aio with a few covers and 12 prefolds. so far I have 14 aio.
