First of all if your dh has food allergies then your dd has a higher chance of having them. Your dd also has eczema which can be caused by food allergies but not always, other things in the enviroment can also cause it to flare. My son reacted to avocado the first time we tried it, his eczema flared on face almost immediately and it went puffy.
I hope I have been of some help.
