I had a quick look on the net and was confused. I know you are meant to delay nuts till children are older, is it 3 for say peanut butter and 5 for whole nuts, I know I read it somewhere. But pine nuts are not actual nuts so are they ok? They are in a recipe I'm cooking and also in pesto which I thought my son may like although it may be a bit salty. There are no nut allergies in my family but I do have dust allergeries, hayfever etc.
