Nothing wrong with jarred baby food. Apparently, the costs of organic produce in your area is quite high. The primary advantage of making your own food is cost, so if you want organic and it is that pricey, stick with the jars.
In most of the world, baby gets whatever is for dinner for the rest of the family. Just puree it appropriately. A hand blender works great for this.
I felt I should add that I personally don't like the fact that baby food is now being packaged in plastic instead of jars. While I understand the expense involved in jars, I think parents should be given a choice between buying infant food in jars vs. plastic. In the long run, I think that is bad for the consumer of baby foods. I would personally stick with jars.
