We've always been an "on-the-go" family. My children on occasion ate jarred, usually organic baby food but I never felt good about it. It was for convenience sake. Then I learned the trick of FREEZING it into ice cube trays and creating individual portions for easy transport.
The basics of making your own baby food is to steam the veggies until they are soft enough to mash or puree, add protein if they are at "that stage" and give them lots of variety. My kids always loved carrots & squash combined, or blueberries & apples combined. Be creative and open your child up to a whole world of new and wonderful foods!
