Good for you!!! It is SO easy to get started. First, I'll send you a website of a friend that has done EXTENSIVE research on feeding babies and is my personal guru on the subject. It is her blog called CUTIE PATOOTIE FOODIE -- adorable isn't it?! She's the mom of three, two girls and now a bouncing baby boy to add to her clan. Look at her OCTOBER entries that list the baby food introduction chart (researched and pediatrician endorsed).

Basically you just steam fruit and veggies (think of natural combos or even cruise the baby food aisle for ideas) and put them in a food processor or blender. Then put them in ice cube trays and freeze immediately (unless you want to save a portion to feed that day. Cover the ice cube trays with press and seal, let them freeze. Next transfer them to a freezer baggie, label them with the date they were made and the contents and you're in business!!
There are lots of books out there, and I think one that I have is called Top 100 Baby Purees, Super Foods for Babies and Children. I also like Deceptively Delicious for older kids, and once you get the hang of making purees, you won't need any books.
The great thing about making your own purees is that you can also make your own custom mixes. Just use two to three "cubes" and that is a pretty good portion for an infant. My babies also love yogurt and soft cereals (even malt-o-meal or cream of wheat is perfectly fine for babies). Yo Baby is great, however it is VERY thin and runs a lot, so use a bib or even thicken it with a bit of baby cereal.
Have fun!!! Oh and one thing that my youngest loved as a baby was when I took a bag of frozen veggies or fruit and dropped it on the counter to break up the pieces--it left him giggling for a long time!
