Dd has a dairy allergy - congestion, eczema, explosive green poo followed by painful diaper rash, the works...
Neither of us have had any dairy, but she had one of those diapers and rashes yesterday. The only thing new she's had was blue dye - I made her frozen yogurt dots (where you squeeze dots of yogurt on wax paper and freeze them) and since the coconut yogurt (which she's had before) is white I thought I'd make it more fun and added a drop of blue food coloring to the yogurt.
Well, she ate a ton of the dots (about the amount of yogurt that an individual thing of yogurt holds) and then a couple hours later had that diaper and she still has the rash. She'll barely let me clean her when I change her diaper because it hurts her and it's the exact type of rash she gets when she eats dairy.
Anyone else experience this? I found some info online, but most was about dues causing hyperactivity and behavioral issues and those are usually from red and yellow dyes.
