mommies how many boxes of diapers should i get to last me 4months.... and what size

A lot. I don't have an exact number, but we go through 8-12 a day and she's 3 weeks old.

* 8-12 diapers a day

Might want to get 2 different sizes if you're trying to buy in bulk. Never know how big baby will be or how fast baby will grow out of one size into another.

one box of newborns, three size 1s and two size 2s

well my daughter started in newborn is 3.5 months and now in 3s so I agree with @ce5ce but I'd add one box of size 3s just in case and it's not like you won't use them or if you have unopened extras just take them to Walmart and get a bigger size

@ce5ce, @steph11 🙌 now those are real helpful answers thank you!!!!

no problem

oh 1 box of 200 lasts us a month. if that number helps better we buy the bulk boxes
