There have been a few reported cases of toddlers and babies getting chemical burns from wearing Pampers baby diapers but a lot of babies and toddlers wore and still wear the pampers baby diapers today without any chemical burns.
I think the problem is the child is allergic to whatever chemical is in the pampers baby diapers and they get the chemical burn from the pampers as a result.
I've also heard of few cases where babies got chemical burns wearing huggies brand diapers as well.
If your child is getting chemical burns from diapers you might have to switch to cloth diapers which are better for your baby and are much cheaper too.
Honest diapers are also better disposable diapers that are chemical free.
