First things first. Every maternal economist must have a coffee grinder (i.e. grain and bean grinder). Hand grinders and large electric grinders are important, BUT for daily jobs it is so much EASIER, CLEANER, and FASTER to pull out a tiny coffee grinder, push a button for a few seconds, and be done. I literally use mine every day. It's worth far more than it's weight in gold and you can buy them for any where between $20-$40.

Now for the baby food recipe. You will never go back to refined rice cereals again. I say this on the assumption you already know why whole grains are so much better for your babies than refined. Without belaboring obvious knowledge, let's just say "they" may add nutrition back, but it's a VERY SMALL percentage compared to what they've taken out, let alone all the other things they've taken out. This topic should be a post in and of itself. Anyway, below you can see how easy it is to fill the grinder with grains, push the button, and voila, instant baby food powder.
Babies need to start with rice as their first grain. Therefore, buy brown rice as it has superior qualities to white rice. Use brown rice solely until your baby has established it internally before adding additional grains. Oh yes, the recipe. I nearly forgot, it is that simple and easy.
One Serving Baby Food:
1 Tablespoon grain flour
1/2 cup water
Stir flour into water with whip until boiling. Let cool until warm. Add smashed fruit or veggies. This literally takes a couple minutes from start to finish.

After rice has been established, add millet, then barley, and then oat groats. The combination of all those grains is what you're after, but you do have to wait a week or so before adding each of the additional grains. My babies tolerated each additional grain fairly quickly so I didn't wait that long between additional grains. Don't believe it? Look at my babies; they're beautiful, vibrant, and healthy! This cereal was THE MEAL every meal for my little babies, varied only by the different fruits or veggies added to it. Cost? I buy my grains in huge quantities. I'm too lazy to do the math, but pennies, and it's a meal that makes a super mom and super kids.

I only have experience with the Bosch coffe grinder and have loved it for years. I posted the Krups one below additionally only because I noticed it was a lot less money. I'm not sure how they compare.
