I also use the ever-popular Penaten Wundschutzcreme for my little girl because it adheres very well and helps. I use it mainly at night when my baby is sore, because just at night she has the diaper longer around and through the Penaten cream comes no new moisture on the Popo. About the ingredients was now already go and disskutiert in all forums. Whether harmful or not, ultimately everyone must decide for himself whether he uses it or not. I can only say, my mom has been used when I was a baby and I'm still alive. The cream helps super with my daughter, but I also use it only if it is sore.
A little tip: I use it not pure. I mix them with Penaten-panthenol cream, then it is not so thick.
