Can you make homemade baby cereal?

Single grain cereal (ie rice cereal) is generally the first starter food that most parents go with.  Many professional resources also state that foods such as sweet potatoes, avocados and bananas also make great starters.  So although I am not ambitious enough to make baby cereal, it can be done.  Here is a link to a helpful site with instructions on how to go about it if you do decide to go this route.
