Sorry about Kylee's diaper rash. Hope it clears up soon!
The only things that really helped Leela were
1. Lots of naked bum time
2. Baking Soda sitz bath
3. Lanisoh (yes, the boob stuff)
When it was really bad i used a hair-dryer on the low setting to dry the area completely with each diaper change. Also stopped using fleece till it cleared up.
Rachel, the breastmilk did not work for me. :(
But Leela got a kick out of me spraying her all over the place...hmmm maybe i should have just expressed some and then used it.. silly me.
