Mine had smooth peanut butter before one, but there is no history of allergy here. Nuts themselves I haven't given til 5 because as far as I know they can't digest them.
Maybe you could go to your gp & ask for allergy testing. It'd be better to know now than have her eat something at school or somewhere & have something happen.
Plus alot of foods contain traces of nuts & its easier to know to look for that sort of stuff as she starts eating different types of foods
