My baby is 6 and a half months, and he has never had a diaper rash! The fact that he is teething and still there is no sign of a rash, is amazing! I think diaper rash is one of the worst nightmares for parents, especially if it's a severe rash. I've seen those - not a pretty sight :( So what's the secret you might ask? I've been using Mustela Diaper Rash since Day 1. I was recommended the product by my European friends who swore by it. So, I gave it a try. Since then I've been using it daily on my baby boy even without any symptoms of a rash. I truly think that this cream is a miracle worker. It's easy to apply and remove and it definitely provides an adequate barrier. Use it at the first sign of redness, and the redness will be completely gone by the next diaper change! . I have found this cream to be extremely effective. It also lasts forever. I just use a little bit, and it works. recommend it to everyone!
