Hi Lucy,
Making baby food is very easy! The best tools for the job depend on how you'll be doing it...
If you want baby to eat what you eat, just buy a little food meal and grind right at the table at meal time. I've seen some for sale on the baby aisle at Whole Foods.
If you want to make large batches to freeze (what I did) a food processor or blender would be a good choice. I have both (a Cuisinart set with one motor base for blender/food processor options on top http://www.amazon.com/Cuisinart-BFP-703-SmartPower-Blende..., and never noticed a major difference between how well either setup worked. Just take a look at the size of the work bowl/pitcher when you buy. My food processor work bowl is only 3 cups. Not enough. I had to puree in batches when I was pureeing, say, a whole squash.
Also, you will want a steaming insert. They are inexpensive and make cooking veggies (and hard fruits) a cinch.
One other piece of advice: ask your pediatrician for a list of which foods to introduce in which order. You can also go to the library and check out a couple of baby food cookbooks. "Super Baby Food" is a great reference but is tough to navigate. The "Everything Baby Food" book is very simple, maybe too simple. Books by Annabel Karmel have great combo meals for when baby is a little older, but she sometimes doesn't line up with age recommendations for foods (like nuts and fish), so you'd have to do a little research.
Good luck and enjoy!
