Something to be worried about or not?

I have just been eating some walnuts, DD1 (2 yo next month) got hold of one, I managed to get it off her before she ate it as it was a full half of a walnut. She has now come out in a spotty rash on her left cheek.

Not sure if it is anything to do with the walnut or not, it is the first time I have eaten nuts around her and I didn't so much as look at them while I was pg with her or while BF'ing her.

Not sure if the rash is something else and is more of a co incidence IYSWIM. She is not teething and has not eaten anything new.

Oh and she is fine in herself IYSWIM, no problems with breathing etc.
