Agree with all the advice offered no need for an ID to get on a plane... but you never know when you might need a "gov't issued ID". So we spent a little time at the DMV and got state issued ID's for each kid -- and in doing so now we don't need anything else for school, travel, etc. Of course, you'll need certified birth certificates, social security numbers and proof of address to get the state ID card ... but once done, its good for 5 years in this state.

Plus, if TSA gets a wild hair up their butts, and decides to require ID for kids, we're covered.

And if we have trouble on the road (need a doctor, hospital, etc.) we don't have to carry the birth certificate, social security card, etc. Reduces a lot of potential trouble....
