We don't keep soda in the house at all... but I don't restrict the kids from having some if they're offered it. Sure, it's not a healthy every day thing, but like ice cream, once in a while is just fine We don't generally keep juice in the house either - nutritionally it's so much better to just eat the whole fruit.

We ALWAYS had soda in the house growing up... but even then I don't remember drinking much of it until college when I got hooked on Mountain Dew.. but soon after I discovered coffee.. and I rarely drink soda any more
