Baby Food: Sweet Potatoes

I decided early on in my pregnancy that I wanted to make Jr.'s baby food, more for cost savings than anything else. I can buy a 5 lb bag of sweet potatoes at Sam's club for just under $4. I found a price online where a grocery store was selling a 4 oz. jar for $1. My last batch of sweet potatoes yielded 74 ounces. That's about $0.05 per ounce. If I bought the same amount in a store it would have cost me $18.50. It's not quite like calculating the cost savings between breastfeeding and using formula, but it still adds up.
