I am glad it is looking better and it doing so that quickly tells me you where probably dealing with a very minor diaper rash type thing or possibly separation going on.

I agree with other PP that the amonia smelling diaper could very well have caused a diaper rash. I've had those with my kids, the amonia smelling diapers that is. A couple times my intact 4.5 mth old has had a redness to the tip of his penis, I just assumed it was from the sitter maybe leaving him in his diaper too long (paper kind) as I've already discussed with her about not retracting the skin.
