Baby won’t eat

My son will be 11 months in six days and he has never liked food. Yesterday I was so proud of him because he actually took a couple bites of some shredded cheese And a chicken nugget. I’ve been told you should be eating at least three meals a day and only having three bottles But all he wants is his milk and throws a fit if I try to get him to eat anything. I will put him in his high chair and put some food on his plate he doesn’t care for it and eventually starts crying or throwing the food off his tray. Now he hasn’t ate for six hours he woke up had 7 ounces of milk That was six hours ago. I tried to put him in his highchair and put food on his plate he doesn’t want it and he cries and I don’t know what to do. I don’t want to keep giving him a bottle but I don’t know if I should just keep them in his chair until he eats or what I feel defeated and horrible. It literally Frustrates me to the point of tears every day.
