My first son had hardly any store bought baby food. Mostly because I was really cheap!
I just cooked down veggies (carrots, peas, green beans) or fruits (apples, pears), blended with a little bit of water, and froze them in ice cube trays. Easy! Ice cube trays are great. I popped themout and stored them in gallon size ziploc baggies, labeled; carrots, peas, etc. That way I could as many or little as needed. (I also do this same system with homemade chicken stock!)
I sometimes added a little more water and rice cereal. With canned fruits, I just mashed them up and served. It's super cheap to make baby food. A friend of mine owns a restaurant and she made her son all kinds of gourmet baby food. There are such great books out there too. I've gotten great recipes from books for toddlers that have become some of my favorite meals for the entire family!
