Hi My Name Is Ingrid, I Have A 10 Month

hi
my name is Ingrid, i have a 10 month old baby who is still breasfeeding. i tried giving him NAN optipro and then he he started to get Hives and his lips started to swell within a minute. i know he is allergic to gluten but im not sure about milk because most of his purity foods has cows milk in them but formula is not good for him. i also bought NAN H.A and it taste so bitter and he doesnt like it. i was thinking of introducing Nido when he turns 1 but im not so sure anymore. please help
