I swore by zinc and castor oil cream when my DS was a baby. I used to ensure though, that after I wiped him clean with a wipe, I patted him dry with a tissue then applied the zinc and castor oil cream. We didn't have a single occurrence of nappy rash.

My sister found that because she didn't dry her DS off and just used a wipe then slapped cream on, her daughter suffered from nappy rash as the environment was basically warm and wet the entire time. I think at least when you're dry and a barrier is put on, you have less chance of irritation occurring.

Thanks so much for the heads up about those products containing nut oils....it's very handy to know.
