Diapering can be an interesting challenge if your child has ostomies. Vesicostomies can usually be covered with a regular diaper maybe one size larger. Pyelostomies are higher up and on the sides/back, so they are harder to cover. For the smaller babies, just using a larger size diaper can work, but soon they will be too big for them too.

For pyelostomies, you can use a regular diaper wrapped around their back and then use a youth/adult diaper on the regular way to hold it on. You might need to tape up the leg holes a bit (another use for duct tape!)
