Aveeno products are best and in the case of wheat or nut allergies be cautious about it.
I cannot praise the stuff enough no more pain and the redness just goes away in hours
Aveeno is great, and child's farm is an excellent moisturizer for wee ones. I actually use it myself as a daily moisturizer because it's so gentle and a little goes a long way.
I would be careful with Sassy's recommendation for using coconut oil. Please, please always swatch a patch of skin before using coconut oil. It's actually allergenic for many people with skin conditions - something I didn't know until I slathered myself in it after someone said how good it was and I had such a severe reaction that most of the skin on my back came off in big patches and blisters, it was like burns.
I've used Lavander essential oil diluted of course. I recommend using coconut, sweet almond, jojaba, and /or sunflour oil as a carrier oil.
