DS1 is allergic to eggs and nuts. DS is 4 months old so i plan to start weaning him in a couple of months. SHould I get him tested (at the same time that DS1 has a check up for his allergies) before I even try DS2 on food like dairy/wheat etc? Or should i just treat him like a "normal" child and try foods with him as you would with a child with no family history of allergies? At the moment he is exclusively breastfed.
