A.,
try cloth diapers
I used little g pants and diapers
they are very similar to regular diapers BUT the diffrence is the COTTON touching her bottom,
My kids are allergic to the material in the diapers and blister up because of it
I use Nystatin cream for the yeast, and Dr boudreaux's BUTT PASTE from walmart it smells good, and is sort of oatmeal ish
but is works good,
Also try giving your baby some yougurt the active yeast cultures can be helpful.
try dipping the babies bottom into the water at each change,
and NOT using a wipe,
PACK a few wet washclothes into her bag for the daycare to use
tell them you think its an allergy
they can toss the clothes if they need too,
But like i said what worked for me was CLOTH DIAPERS

initially it costs more money up front, but long term its cheaper, NOT messy because you dispose of the insert
and i haven't had any rashes like THAT since.
I also when home use a prefold cloth insert sold at walmart
for pee's
and with poos just dump the poo into the toilet,swish the dirty cloth diaper around, to rinse it off, I have a special garbage can int he bathroom for the cloth diapers,
and wash them separately. BUT i am a stay at home mom.
Its really not as difficult as you might think, and no more nasty than rinsing off a poopy wash cloth.
PLUS every one thinks they are super kewl

OH and triple paste samples from your doctors office is good too.
