Are nuts ok if DC does not have peanut allergy?

For some crazy reason DD loves walnuts.
I was putting them in my yogurt last week & she was harassing me for them.
I gave her a tiny one & she's been screaming for "nuts" ever since!
She's pretty good with chewing so I'm not too worried about her chocking.
Since I know she's not allergic so is it ok to give them to her?

btw- she's almost 19 months
