I agree kids do need a bigger size of bed wetting pull up and all companies should go up in sizes for the bed wetting pull ups as it would be helpful.
It's probably because they don't think there's a market for the larger bed wetting pull ups.
However I was in the store today getting my 5 year old son some diapers for his bed wetting and noticed they were selling a size 8 Pampers Swaddlers diapers.
He wears a size 7 Pampers Baby Dry diaper for his bed wetting as he leaks out of the pull up kind.
The Pampers Baby dry size 7 diapers fit him good and they don't leak like the pull ups and he's okay with wearing them although not all kids will be okay with babyish diapers.
The size 8 would be too big for him.
So if Pampers is making a size 8 diaper then there has to be a market for them as I always notice they are out of stock so maybe some older kids are wearing them for bed wetting or incontinence.
I also notice the dollar general store here is always out of stock of their Gentle Steps size 7 diapers which is what I normally would use for my 5 year old son for bed wetting but most times they are out and I have to buy him the Pampers Baby Dry size 7.
It would be a good idea for the other companies to make larger size bed wetting pull ups and hopefully they will soon.
