I took a look at the diaper and noticed why, they old diapers had an inner liner that went nearly to the top of the diaper in the back, the new ones only cover about 60% of the diaper from front to back so when the child is laying down on her back the
diaper allows leaking like crazy!!! I wrote to
pampers about this and they promised me 2 free packs but I have yet to receive them and that was about a month ago.
