You only spend $70 a paycheck on groceries.

We buy food for us. Diapers, wipes, baby food, extra formula because WIC doesn't supply enough. Also things we need for the house like dish washing detergent, Dreft (which is crazy expensive) and other cleaning stuff. Plus, he has to pay child support for his first kid, and gas for him to get to and from work (and our trip to your and my parents city killed us), plus bills. So.. money goes quick.
