Peanut Allergy?

I gave my 9mo peanut butter for the third time today. The first two times it was a tiny amount by itself on a spoon. This time I mixed a teaspoon into some yogurt and let her self feed. Quite a bit got on her belly and now she has this rash all over her torso (front and back).

No vomiting, wheezing, or any other symptoms. Our after hours doctor line said this sounds non emergent and to call the GP on Monday if the rash doesn’t clear.

For anyone whose kids have peanut allergies, did your kids experience anything like this? (I’d appreciate comments from people who have experience with peanut allergies, not just conjecture 😊)
