Unfortunately, peanuts and peanut butter aren’t healthy food choices. You can learn more about that in my article about the best nut butters. In a nutshell (pun intended), peanuts aren’t nuts but legumes and they contain significant amounts of antinutrients. Additionally, all peanuts are covered in a toxic and carcinogenic mold called aflatoxin. For these reasons, I strongly recommend not offering your children peanut butter on a regular basis — as delicious as it is.
