Hi A. - My son who is 14 months has very similar problems. He is also allergic to Eggs, Wheat, Peanut and mildly to Soy and Corn (Soy and Corn causes him to break out in a rash if he eats too much). He's also asthmatic. I was never able to really breast feed full time so he's pretty much a formula baby and I really think he has seasonal allergies. Especially right now because he's stuffed more now than ever. My allergy doctor has my son on Zyterk and Singular. The Singular seems to be helping more now but also using a saline mist spray at night also seems to help a little - it'll make his nose run a bit but at least it keeps his nose moist vs it drying out and he seems to breath a little better. I do warn you that my son hates this but if you get a fine "baby mist" it appears to be better and more gentle. I hope this helps and good luck.
