My 3 year old is IGE to egg, CMPA and has now thankfully outgrown wheat allergy.
Research suggests that siblings are likely to have allergies. I’m pregnant with my second baby and wandered what others did, regarding breastfeeding and avoiding certain foods towards latter end of pregnancy in readiness of the birth of my second child, incase second child also has allergies.
My son was a really hard work baby, and was having typical allergy reactions through my milk (without me knowing at the time, until he was weaning onto solids)
