Its best you stop of the formula first. Some formula doesnt suits to our child which might need to change of formula or there will be some reactions just like my son n daughter had. My son having this reactions of insect bites but truly its from the baby formula that we gave him. My daughter had alike of eczema attack all over her body. But none of us have this history which cld effect on our child. So we stop giving her the formula and eventually it stops.
