is it OK if my son doesn't take milk anymore?


So my son is drinking cows milk, he's 11 months old, once we changed to cows milk he loved it! Milk was everything for him! But for the last week my boy refuses to drink milk, he prefer to drink juice or any other drink except milk, he eats normal food. He takes few sips and then he puts the bottle away, he has tiny cold, but it's going away, I thought maybe it could be the reason, but now I'm not sure.. Is it OK to stop giving him milk that soon?
