Are Sweet Tooths Hereditary?

Anyone who knows me well knows I have a love of sweets (really, mostly chocolate). But my kids are taking it to a whole new level. I think I have been pretty good about giving them junk. They eat really healthy except for the occasional dessert after dinner or sweet treat from Daddy. It's like they can smell sugar out or something because they find it, wherever they can. And when they see something sweet it's like all control and reason leaves them, no matter what they know they should do, and they eat it up like there's no tomorrow.

For example:

At different times throughout about a weeks time(a couple weeks ago) they found Daddy's stash of skittles and ate it by the handful until I found them with sticky hands and eventually til it was gone completely. And the other day I cam upstairs to find them in Grandma's pantry holding bottles of sprinkles and pouring them down their throats. They were passing it back and forth gleefully. You can see they emptied one bottle of the long multi colored ones and would have finished the others, I'm sure, if not for the smaller holes that were clogged by their saliva.

I've caught them red handed so many times I can't even remember them all anymore. I mean really, I thought I liked sugar so much because I ate desserts way too often growing up, but since they don't have that issue I think it must be in their genes!
