I would certainly not presume to tell someone how to organize their family's finances. However, if you want to make it on a single income, let's face it: you have to economize! There are lots of ways to do this, and everyone has their own preferences. Here are a few tips.
The first and most important thing is to learn to do without. This takes practice. Keep in mind that as you, the parent, learn to do without, your child learns from you. You don't need every article of clothing in the store or every new gadget and they don't need every toy. This can be difficult if you have a weakness for certain items (like shoes...). However, if you don't learn to do without, you will not make it on a single income.
If you have to have everything, then you have to pay for everything too. Ask yourself what is more important: stuff or the well-being of your kids?
It's amazing how far the concept of doing without can go. Examine every spending decision. Do you need that new car, or can you squeeze a few more miles out of your current one? Do you need that house with that size mortgage payment, or are you managing in what you have? Do you need that big TV, or will a smaller one suffice? How was your grocery order this week? Did you buy a lot of extras that you don't need? Believe me, as someone who does it, I know this is hard. We live in a society that has come to view "moving up" into something "bigger" or "better" is the way to go. Consider that most of the world makes do with far, far less than what we have.
It's tough, but it can be done.
And all I can say is that growing up, I wore a lot of second hand clothes.
This is another reason why I am in favour of the $100 per month per child option. I can stretch a buck a whole lot farther than the government can.
