The only advantage of making your own over jarred food is cost. Some things, like bananas, just don't require any prep, so buying them is sort of pointless. As far as safety, jarred baby food CAN have recalls, but your homemade organic food can also be contaminated with e.coli. Jarred food is also safer to use away from home. Restaurant food can be contaminated. Your MIL may not cook things to your satisfaction. Your homemade food could melt early and be laden with bacteria by the time you feed baby at the mall.
I would add that meat made at home smells better than jarred meat, but if you have ever canned your own meat, you realize that it is the process of canning that gives that odd odor.

Yeah, right. Some people just want to stay on their bandwagon. Jarred food has changed dramatically in 20 years. Gerber is also organic.
