If at all possible I would get some type of food processor, the bullet is a good example.  This way your baby can eat the same foods you are and they are also getting more of the nutrition.  Not only is it better for your baby but it is also cheaper.

You will be making food anyway, and if you making food for your baby chances are that you will start to eat healthier.  In most of the processors you can put meat in them as well.  Give it a try, and if you like it save those jars of food for other times!
