Hi. Try an infant probiotics to start. I have recommended Liberte kefir for children with eczema so you may want to tyr that if you daughter is eating solid food. If you are breats feeding, then you need to improve your good bacteria levels so that the breast milk delivers better levels to your daughter. It is better she gets the good bacteria from the kefir than through you as it will work faster but she may not be ready for it. There are topical homeopathic remdies to help with the irritation. Go to your local health food store and they can recommend a product. A lot of practitioners will tell you to remove foods but that may not necessary as having an issue with a food is caused by the same imbalance as ecaema which is poor intestinal flora.
