How old were your kids when they first tried their first fast food?

Babies are smart little sweeties -- they just know what the good stuff are haha. My friend has to eat her fast food away from baby because even though he has never tasted it before, he seems to want her burger or fries every time she brings it back home. Maybe the smell of the fastfood is addictive? She does not want to let him try fastfood till he is atleast a year and a half or two. So for now, she'll avoid bringing home fastfood or eating at KFC or something when they are out haha!
