I bought a lot of stuff at garage sales when my DD14 was little. We cut way down on eating out, we limited it to just once every few weeks. We were on a tight budget, like down to the last penny each month. I also only bought food that was on sale and made my menu from that. We kept the air on 80 during the summer and 65 in the winter. I also breast feed which cut down on the cost of feeding the baby.
