I get them from oranges, mango and now any stone fruit. Have had them so bad they just about joind each other.
It took me a while to work out the reason and now I just don't have anything that I think will trigger them.
The weird thing is that I can have lemon
What you are giving her works well and keep the bath water tepid.
Most of the time it's a case of hit and miss until you find the trigger.
