I have a baby who started food allergies at 5 months from formula in his rice cereal, I hear your concern. He is anaphylactic to tree nuts, eggs, dairy and has over 5 other sensitives too other food. You can try a spot test where you put the peanut butter on the baby’s skin and cover it and if he gets bumps or angry skin you your know he could have problems. My baby 23 months now if he touches dried milk he brakes out in hives like crazy! Good luck! Food allergies are so hard!
