Cereal has less calories and nutrients in it than formula, so if you give him cereal, it will displace the amount of formula that he takes in, and in fact he will consume LESS calories. The reason people think that the cereal works is because it takes more time to digest than the milk, so his stomach will be "full," but he will have consumed less calories and nutrients. Imagine his stomach is a measuring cup, that can only fit in a certain volume of stuff. Say you fill it to the top with 1 cup of formula that is 100 calories (these numbers are just chosen for the example). Now, say that you add cereal, that is worth 50 calories per cup. To add the cereal to the measuring cup, you need to displace some of the formula, right? Pretend you take 1/4 cup of formula out and replace it with cereal. You've just taken out 25 calories and replaced it with 12.5 calories. Not a fair trade. Solid food is meant to supplement, not replace it.
