Quoting ♫ boobook ♫:" <blockquote><b>Quoting Tiger Lily ♥:</b>" Get some generic zinc PASTE. It's paste ... [snip!] ... a wash cloth or rag. I just used destin cream the purple tube, super thick. And I ran out of the good butt paste yesterday."
With my nephew and my son, I always found that the thicker the paste...the better it worked. It protects the skin, so that pee and poop can't irritate it even more. I'd give him some more air out time and see how it looks tomorrow. Desitin and A&D for Babies never worked for me. :/
