yes it can be the wipes I use pampers wipes all the time and they have me Huggies wipes so I used those and she started getting a rash so I figured it was that so I changed them and it was gone. and the diaper cream worked great I used dr smith

@mj3, I use jock itch cream n vaseline, works wonders!!! I don't use any scented wipes

i could be the wipes, diaper or the cream just isn't strong enough. when my son got a bad rash i changed him every hour to help get rid of it and they say to use a wet papertowel because the scented wipes can make it worse.

Try just using wash clothes and water, like you did when he got circumsized (if he did).
