T.S.
It definitely could be eczema so taking her to see your doctor is a good idea. Most cases of eczema are a reaction to a food (other reactions include diaper rash, dark circles or puffiness under the eyes, irritability/excitability, etc). She could be reacting to a food you recently introduced or maybe something she has been eating for a while that has been slowly building. The most common food allergens are dairy, wheat, eggs, citrus, and soy. If you are nursing she could even be reacting to something you are eating. If the doctor diagnoses it as eczema there are lots of things that you can do to figure out what the cause of the problem is instead of just treating symptomatically with steroid cream (which is the usual prescription). Suppressing the symptoms just allows whatever is causing the problem to fester and ultimately lead to some other problem that is typically worse - like asthma. Please feel free to contact me if you have any other questions about non-steroidal ways of dealing with eczema (if that's what it turns out to be).
