how many wipes do babies go through
That is a good estimate at 3000 diapers / child / year. Wipes very so much... on older children I use them for sticky fingers and runny noses. I think I am likely to use 10,000 wipes the first year. So for disposables and one baby I would say 3000 diapers and 10,000 wipes for the first year.
I use one wipe for pee diapers. I do breastfeed, so my baby has a poopy diaper at least once a day. I can use anywhere from 3 to 10 wipes for poop. There's also using wipes for spit-up. I'd say about 3,000 to 4,000 diapers the first year, and around 8,000 wipes.
