Question
My child tested positive for several allergies when he was a toddler. He is allergic to peanuts but has eaten food with peanuts since. He’s outgrown his egg and milk allergy. He also doesn't break out in hives now. But has he really outgrown these allergies forever?
Answer

If your son can eat a full serving of peanuts or peanut butter, it’s likely he’s now tolerant to peanuts. That said, it’s possible for the allergy to come back. The risk of this happening would be very low --especially if he is eating peanuts regularly. This may help maintain his tolerance to peanuts.
