Wow! My kids are all practically young adults now so I never heard all this "veggies first" or allergy concern stuff when they were infants. But some of it makes sense. On the other hand, all my girls started on fruit mixed with their cereal and I never had a problem with any of them preferring fruit/sweets over other foods. The notion of veggies mixed with cereal is enough to make me toss my cookies. LOL!
It is my opinion that a meal of cereal (with or without anything mixed into it) in the evening helps babies to sleep contentedly through the night.
