H.P.
If you're breast feeding, I'd guess it's a slight allergy to something you're eating. If not, maybe it's the formula.
Also could be the lotion you're using or the baby lotion. Try a detergent w/o any perfumes, etc...like All Free. We use Charlies Soap. It's dye free, allergen free, etc. for lotion, try California Baby or something that doesn't have a lot of perfumes.
I hope it gets better soon!!
