This is a power struggle. My daughter was completely on table food by 10 months with only 2 teeth. Stop the baby food, give him whatever you eat (mashed up if you want) and let him feed himself. At 14 months, a lot of kids throw food on the floor (which is not okay). Stopping baby food is not going to traumatize him. When he gets hungry enough, he will eat. No more cookies, by the way. Don't give him a lot of different things right now. That's too confusing. What are his favorite baby foods? Give him one or two of those in table food until he starts eating. You must be consistent. When you get rid of the baby food, get rid of it - throw it out so you won't be tempted. And, don't fill him up with milk. It will be hard but you can do it.
