Help with 20 month old only wanting milk/bottle?

My 20 month old only only wants milk and only wants to drink it out of a bottle. He just cut 5 teeth back to back and was sick (4 were molars). I just got him back sleeping through the night. But he still won't eat much when I place him in a chair. Sometimes he may have a little egg/bacon/tomatoes/chicken. I give him a cup at mealtimes but he won't drink it. But most meals he is just missing. He does consistently want his bottle of milk after meals. Does anyone have a great way to make this transition a little easier than cold turkey that will result in a lot of crying. I thought of watering down the milk - does this work?
