My youngest son, #3 has a peanut and orange allergy. Turns out the hives and constant sinus issues, dark circles, etc. were caused by peanuts and oranges. None of the boys has a severe allergy, thankfully. But it's enough that they each have to be aware of what they eat. #3 has taken the dietary change quite well. He can have other nuts with no problem, and has since discovered that he loves cashew butter. Unfortunately that is an expensive nut butter, at $7 for a 12oz jar. While he was in preschool, he had become very responsible about his allergy. At age 4, he would scold the cafeteria ladies if they mistakenly put oranges on his plate. He's 5 now and about to go into Kindergarten. I will have to be more diligent now as parents bring in snacks for the kids at class parties.
I have learned how to make my own pop-tarts, using pie crust and jam. Next I want to try making my own granola bars, peanut free. Eventually I will learn how to make a proper loaf of bread. For now, I will just have to get a Costco card and make the 90 minute drive twice a month to buy bread. Lots of bread.
