Hi,
I would be more than happy to share info on making your own baby food. I made my son's baby food until he was ready to eat whole solids and started eating what we were. First though, most doctors won't recommend that you start feeding solids until your son is about 6 months. It will prevent future food allergy issues if you wait until 6 months.
To make home baby food you really only need 2 types of special equipment - a blender or food processor and ice cube trays. Since you introduce foods one at a time, it is easier to make a big batch of something, freeze it in individual servings and then defrost it when you are ready to use it. Even once you have a lot of foods in your son's diet you will still want to make things in large batches. Basically, it's really easy to make baby food. You just boil or steam it and then puree it. Most people start with fruits and veggies like sweet potatotes, carrots, apples and berries. Depending on your personal preferences, you can also choose only organic foods from organic stores.
Let's say sweet potatoes.....I would start by boiling one or two potatoes, depending on how big of a batch you want. Once they were fully cooked, I would drain them and put them in the food processor. My son had some weight issues, so as I was blending, I would use breast milk or formula to help liquify as it was pureeing. If you don't want the extra calories you can just add water. Most people like to add the water they boiled the veggies in, thinking it may have more flavor than plain water. Then once everything is pureed to the consistency I want (at the beginning things should be really liquidy, but when your son gets older you can make things thicker) I would scoop it into the cubes of an ice cube tray. If you get the more square shaped cubes, they are about an ounce each, which is about one serving when your son is young. Then later that day when the food was frozen, I would pop the cubes out and put them in a ziploc bag.
I would do my cooking during the weekend and I would do multiple types of fruits and veggies. THen throughout the week I would just pull things out of the freezer. As your son gets older, you can add spices like cinnamon to apples, etc. Also, you can start mixing things together like fruit combos or veggie combos. The only thing I never had success with was meats. My son never like the texture of the meats that I was able to make. SO, I ended up buying those from the store.
Good luck with whatever you choose.
