You should probably see your doctor as soon as possible as my child is 15 months and has been eating solid finger food since he was 8 months he also I must add has had 10 teeth since then and 15 going on 16 now.
My child does not eat first thing in the morning so we bought him a toddlers sports cup which is similar to a bottle and he drink the 8-10 oz cup then an hour later the sitter give him a breakfast of eggs, bacon, toast or pancake or french toast or sometimes cherrios with milk and fruit or oatmeal, etc.
Try giving him something new like real oatmeal and blueberries or strawberries for him to pick up granted he is not allergic.
