-1 tub of Aquaphor (you can find this in the moisturizer section of Wal Mart)
-Empty half the tub or so of Aquaphor into a separate tupperware container.
-Add Mylanta slowly until you reach a creamy consistency (I would guess it was about 2 parts Aquaphor to 1 part Mylanta)
-Stir like crazy.
-Apply at every diaper change if your baby's tush is chapped, or just at bedtime otherwise.
I love that it is almost odorless, and it has really helped Daphne! Good luck to all you diaper-rash fighters out there.
