Need to switch diapers... Help!!

Samantha • 31 year old mommy, wife and kindergarten teacher.
LO has been sleeping nice long stretches at night so we decided to start using overnight diapers... I tried the Huggies overnights and she got the worst rash I've ever seen. Her bottom wasn't even slightly red before bed and when she woke up it was almost blistering. The doctor had to prescribe a steroid cream because it was so bad. We also want to switch wipes, so suggestions on those would be great too! She has very sensitive skin and we use organic washes and lotions but we hadn't had issues with regular pampers or Huggies diapers before this! Suggestions please!
