Some more good news on the peanut allergy and other food allergy front. In 2015, medical advice changed to : Yes, please introduce tiny amounts of foods such as peanuts and eggs in the first year of life to prevent food allergies. And...since then, the incidence of food allergies, including peanut allergies, in children has dramatically gone down when that advice is followed.
A recent study found that the incidence of peanut allergies in children has really dropped since parents started introducing peanut products in infancy. Introducing tiny amounts frequently of the food of concern (nuts, eggs, etc.) in the first year of life (by 4 to 6 months of age) challenges and trains the immune system.

Unfortunately, many doctors and parents are still not following the advice because it is so opposite from earlier medical advice, which for decades said to avoid, avoid, avoid the food (e.g., nuts, eggs) in early childhood. It is thought that if more doctors and parents followed the new advice for infants, then food allergy rates would drop even more.
By the way, the rate of dog and cat allergies also drops when there is more furry animal exposure in the first year of life. Same reason.
