Rash help!

[nursemama23]

DD has been pooping more frequently the last 2 days, only thing different is I recently started giving her breastmilk from my freezer stash (she is 18 months, weaned at 14 months but has recently had a few colds and I found a stash in my freezer). Could the change in stools be from the change in milk? The big issue is she now has a rash. I don't think it's yeast (not sure how to tell) but guess it could be. I need suggestions on ointment to use that I can get quick. We use CJs and The Balm right now but don't seem to be working

Sounds right that the breastmilk would increase poops.

We love Lanisoh on rashes. No unnecessary irritating ingredients, it helps break down urine, it's so similar to our natural skin oils...

Worst possibility I can think of is she's developed a food sensitivity, to something you ate when you pumped the milk.
