What size diapers do babies stay in longest?

Question

I need to expand my stockpile, I have a few packs of each size, but I'm curious as to which size babies will be in the longest. I know every baby is different, just looking for some advice. Thanks!

Answer

My son was in size 3 the longest!

Answer

3s lol I had both kids outta diapers at 15 months and they only made it to size three , I hope I can potty train this next baby as soon as I was able these last ones

Answer

My daughter was in 4s for months. Their growth slows down as they get older and bigger, obviously, so it would make sense. I wouldn't buy a ton of newborn diapers. If I remember correctly, our daughter was in 1s by the time she was a month old? Maybe a bit older. 
It's hard to remember, as we only use disposables at night and cloth diaper the rest of the time.

Answer

I say 3s and 4s bc that's around the age of potty training
