Household income

If you are a stay at home mom or plan to be, and the only income you'll be living on is your husbands... How much does he bring home monthly? My SO and I are trying to figure this all out. With his new job were figuring he'll be bringing home around $2600 every month. We'll have the normal expenses.. Rent, utilities, groceries, car insurance, cell phones, and little things for the baby. Just want to see how you all get through!
