I exclusively breastfed my 3 as well and introduced cereal at 6 months. They had various reactions to no interest to very interested. Interestingly it was my tiniest that was most excited about food. She is still tiny and adding food didn't help her put on weight, so I don't think she was hungry before (she was very content before as well). She still likes to eat and is still just a peanut! I think there is some research to indicate waiting can affect incidence of allergies and diabeties later in life. I don't know the specifics of though.
