J.,
Great job on making your own baby food. I did it with 1st child and am doing it with my 10 month old too.
Good first foods are peas (you can buy a bag of frozen peas) - boil them and puree them. Do you know the ice cube tray trick? Once the food is pureed, put them into ice cube trays and freeze them. Once they are frozen put them in a ziploc bag with a label that says what it is and when they were made.
A few other good ones are carrots. Peel them, steam them (or boil them) until they are soft and then puree.
Sweet potato. Bake it and then puree it.
Definately use your breast milk to add liquid. You can also use a little bit of the water that you used to boil the veggies in.
We do green beans, apples (peeled and cored), nectarines/peaches (peel and remove pit), pears (peeled and cored), squash, zuccini, eggplant (cut in 1/2, bake and then spoon out the soft parts, and steam broccoli, cauliflower, potatoes, spinach. The "regular" squash that you may want to try next is smaller than the spaghetti squash (more like a "gourd" and can fit in your hand).
Things you don't have to cook are bananas, grapes, cucumbers and avacados. Just mash those things up and serve them!
As she gets older, you can really just use whatever you are making for dinner and throw it in to get pureed. It is sooo easy! Also, breast fed babies actually do well with homemade food because they are already used to the "taste" of all of these foods since your breast milk changes its flavor with whatever you eat. I have thrown a chicken breast in the blender along with carrots.
I think I also went to the store to see what the baby food jars were. So then, I would just buy those fruits and veggie combinations. The book I have is called "Homemade Baby Food Pure & Simple" by Connie Linardakis. Its got some good recipes, but also a great chart that tells you at what age you can add new things. I do mostly fresh fruits and veggies, except for peas. But you can do a lot of frozen fruits and veggies too.
I hope this helps. Let me know if you have any questions!
