Here is a piece of info I found...
"Many parents have been adding cereal to their babies bottles with the hopes that baby will sleep better through the night or because they feel the baby is not getting enough to eat.
If you've heard the statements, "Add cereal to your babies bottle and he'll sleep for 5 hours" or "If your baby constantly wants to nurse or seems hungry, add cereal to the bottle," know that those are myths and not facts.
Your baby gets enough nutrition from breast milk or formula for the first 6 months of life. In fact, many medical experts agree that introducing cereal before 4 months of age can cause food allergies. Additionally, adding cereal to your babies bottle is a bad idea. Period.
Experts like Dr. Alan Greene, M.D. believe that the sucking and swallowing actions are not fully coordinated in some children, which can lead to pulmonary problems because they can inhale small amounts of rice cereal in their lungs.
The American Academy of Pediatrics also advises against feeding a baby cereal from a bottle. The only time feeding a baby cereal in a bottle is when your Pediatrician recommends it to help with reflux, under close supervision of the Pediatrician.
