If you have kids, you know that things will always come up with them that require a payment of one sort or another: summer camps, sports uniforms, clothing, school supplies, holiday / birthday gifts, educational support, etc. The list can be endless. Tracking all of this activity can be a nightmare and can make following a budget very difficult, especially if you have more than one child. In our house, we have a "kid card," a credit card in my wife's name, that is solely dedicated to paying for kids' necessities. Each month we pay off the balance in full so we don't have interest charges and we have an overall monthly budget for the kid card activity that we manage to.
