DS does. His allergies are horrific (in the spring his eyes swell to the size of baseballs, and that is not an exaggeration). The allergist felt strongly enough that allergy injections would help that he actually moved the timeline up--typically they aren't given until age 5 but he agreed to give them to DS at age 4.5. MIL, FIL and DH have all had them and agree that they make the world of difference. I hope that they can help you!
