LOL, the link Aerobit sent me contradicts the advice given by ChassisWelder and ASU2003.
It says not to use vitamin E because it inhibits new cell growth, and that hydrogen peroxide kills new cells. I didn't know that about vitamin E but I've always heard that hydrogen peroxide causes more scarring. I think I'll skip those two for now.
Bag Balm, however, is a wonderful and amazing way to instantly heal a diaper rash (seriously, one application and the rash is GONE... it's extraordinary...) One would think that if it can heal broken skin on a kid's ass so effectively, then it would also be able to heal the skin under their lip, right? I like GG1's suggestion. I think I shall try this.
At the moment I am keeping it moist with A&D (I left the bag balm at daycare). He's super good about not picking at it, so that's a big help too
After it's healed, however, I would like to try something like Mederma. Has anybody had experience with something like this? Something applied to the scar after it has already healed?
Thanks for the suggestions
