Milk rash – which Mustela products to use?

[mishmoshery]

Hi there! My five-month-old baby throws up a LOT, and he's recently developed a nasty rash all over his neck and chin. I try to keep it clean and moisturised, but it doesn't seem to be getting better.

I keep reading about Mustela products, and I'm keen to give them a try. Only problem is, I'm not sure which products are best – or when to use them. (E.g. should I be using a Mustela cleanser followed by a moisturiser or barrier cream? Which ones?)

Any advice would be very gratefully received!
