My son is 5 months old and at 21 pounds, barely fits in 13"x 20" prefolds that claim to go up to 28 pounds. The next and only size up for prefolds is 16.5"x 21". They claim to hold babies up to 40 pounds, but my son has consistently outgrown prefolds at a lower weight, so these would probably only last until 35 pounds. Realistically, he will outgrow the 16.5"x 21" before he is potty trained. We have some bum genius 4.0 in addition to the prefolds, but they only go up to 35 pounds, so they won't fit him through potty training either.
What are some cloth diaper brands that offer sizes going higher than 40 pounds?
