That's true, but you'll have the greatest benefits in the world for those kids! Make sure you get a care-taker's ID (available through your local military bases ID card office when you bring your ID and your son's military Dependent Care Plan) so you can hit the commissary for the food for them. You'll save about 1/2 on your groceries! Truly, it is much cheaper! And you'll get free health care for them, and you can get them on the list for the military's truly excellent child-care and pre-K. Make sure the paperwork is done before he leaves for basic. Contact his recruiter for details and don't take no for an answer. Those kids are entitled to that.
