My son had also disliked to drink milk at his 9 months old. I guess it may due to his gum pain for the teeth coming out. He absolutely refused milk. Fortunately, he liked to eat cereal that I could add milk with it. He refused sucking nipple and put away the bottle each time I gave him. Then I gave him milk by spoon and by cup with drawer in his breadfast. Now he can used to use the cup with drawer to drink milk 5 -7 oz for 3 times. Sometimes he holds the cup himself and find very interested to the cup. However, he needs 30 - 45 mins to finish the milk each time. He needs to rest after taken 2-4 oz and let the wind up. Then he will finish the remaining. I think you may try this method to give milk to you son and help him find funny in milk time. I hope you will success. Add oil!!
