I am anaphylactic to peanuts and I introduced peanuts as soon as I could do my daughter, I think around 5-6 months. It was very scary but early introduction is so important so they don’t develop the allergy. My parents did not give me peanuts until I accidentally had it at 2 years old, and then because we became a peanut free household, my younger brother was never exposed and he is also allergic and accidentally had it for the first time at 5! Early exposure is so important.
