Have you ever narrowed it down to specific ingredients???!
Looks like DD(8) has an instant but relatively mild reaction to most bubble bath / shampoo / soaps etc
She's ok with Faith in Nature and Sanex Zero so we're good with that but it would be great to know exactly what it is that causes the issue.
She was at GPS at the weekend and they wanted to see if anything they had would be Ok for her bath and we couldn't help.
I've started a spreadsheet with ingredient lists in to compare but wondered if there were well known culprits to look out for???
