Anyone experienced this? I don't know where it came from or how to treat it?

Maybe from her sleep sack rubbing on it? Or drool getting on her clothes? Or maybe milk when they feed her at daycare?

I've tried putting the Earth Mama Angel Baby Bottem Balm on (since I've heard it's good for other things), as well as breastmilk... so far it hasn't gone away but it's only been 1-2 days.

Any other suggestions for what I should try? Should she seed the ped?

Thanks!
