This is something I would usually ask my sister but...?

She is on vacation and I don't want to disturb her with this question. I love popcorn. I've been addicted since I can remember and I usually have some as a snack every couple of days. I can't go to the movies without ordering an entire tub of the stuff for ME only and when I go down the snack/chip aisle in the store I grab a bag or two of cheddar popcorn. I also get popcorn cakes and make "sandwiches" with spouts, cubers even tuna salad. Problem is that my daughter, almost 3 has been asking me for popcorn. I've given her bites of the popcorn cakes and they seem to be okay however I'm not sure if she is ready for popcorn out of the bag/tub and I am not sure if I should try her on it. How old were your kids when they started eating popcorn?
