It is definitely not too young to have allergies. And like jimbob said, asthma can be a sign of food allergies as well. My lo started developing eczema after I started giving her solids. It took a month of eating the food in order for symptoms of the allergy arrived, so you don't always see an immediate reaction. I ended up having her tested and she was allergic to eggs and carrots. I removed the foods from her diet and the eczema disappeared! My suggestion would be to remove high allergens from her diet and maybe yours if you are bfing (eggs, dairy, wheat and now carrots and rice) and see if after a few weeks the symptoms get better. If they do, then you can slowly, one at a time, reintroduce those things into your diet then hers and see when the symptoms reappear again. If this seems too difficult, I would highly recommend taking her to an allergist and having her tested. This is what I ended up doing as I could not figure out the allergens. After going through this process, a few months later the symptoms reappeared and I was able to figure out it was kiwi based on the foods she had already been tested for and the timing of the appearance of the symptoms ( she has also broken out into hives a few times). Sorry if this seems like a long post and I hope it helps. If you need me to further explain anything please ask...but this really sounds like a food allergy that can be easily eliminated once the allergen is determined.
