When Max was diagnosed the allergist told me 80% of children outgrow milk and egg allergies by the time they are three. When he was three and hadn't outgrown our allergist told me he would definately outgrow milk and egg by the time he got to kindergarten. When he turned five and still hadn't outgrown I asked the allergist what his chances were. The allergist just shrugged his shoulders.
There is a new study out saying that only 20% to 40% outgrow milk by the time they reach school-age and only 4% - 26% outgrow egg by that time.
