I did make my own baby food - it was sooooooo much cheaper!! I can't say that I've found any evidence of it being healthier, but in my mind, it is :) We bought mostly organic veggies & fruits - and actually grew our own squash & pumpkins. We started out with sweet potatoes - baked w/a little water or steamed - and pureed them to the consistency of the cereal my son started out with (using a little of the cooking liquid so as not to lose any of the nutrients that may have leached out during cooking). He loved his sweet potatoes! Once we established that he had no allergies to a food (usually 3-4 days later), we started with another food.
He seemed to love everything that was orange or yellow in color at first (sweet tatoes, pumpkin, squash, carrots, etc). He also loved apples. To start, we did not use any seasonings. Once he learned to love the taste of food, we added a little nutmeg & cinnamon to the apples - he went crazy for them! So I did the same with the pumpkin & sweet potatoes - just a little bit of flavor, not too much. And then we could make little baby "combo meals" - and I gave each one a funny name to entertain him at mealtime. He loved "Sweet PoSquApple Sauce" a lot (sweet potatoes, squash & apple sauce). He also liked "Sweet PotUmpkin" (sweet potato & pumpkin). Can you tell he was starting solids in early fall?
We also started on green veggies when he was able to tolerate more txture. Peas are hard to puree and get all the little skins taken care of ... same with beans.
A great first food for babies is avocado - lots of healthy fats, a mild flavor & mushy texture. My son still loves avocado - and I still love to get pictures of the colorful mess it leaves on his face. (he's 14 months now).
My method was always to puree in the blender (again, with a bit of cooking liquid, if available, or purified water) - any old blender will do, you don't need anything fancy - mine is a $12 cheap-o. I then poured the puree into ice cube trays, and when frozen solid, I stored them in the freezer in gallon size freezer storage bags.
As he was able to tolerate more texture, I stopped cooking the fruit and just peeled and pureed it fresh w/a bit of water. He loved mango the best.
I figure I saved at least $20 a week doing it this way - my son is a big eater, and would eat 2 of the larger size baby food's at one meal - and still be hungry (I got a bunch of baby food as a present from a friend, and used some of the green veggies b/c Gerber did a much better job pureeing them than I did). So even when they were on sale (2/$1.00), when you're going through 6 containers a day, that's $21/week in baby food. I could buy a couple of pounds of sweet potatoes and make enough to feed him for at least a week.
Although he is only 14 months old, I am proud of the healthy start I gave my son - he learned to love the taste of fresh foods, and that is something he has not lost. He will not eat the canned fruits & veggies. Some people found it to be an inconvenience - but I found when I prepared foods in big batches, I could get it all done in about 20 minutes a few times a week.
I am not at all opposed to the commercially available baby foods - it was purely an economical decision for me and my husband to make our son's food. We did have some of the premade foods on hand, for travelling, etc.
Sorry for the long post - if you're really interested in doing your own food, I recommend "The Super Baby Food Book" - also check out the following websites: http://www.wholesomebabyfood.com/
