A question for all you mothers out there

So I don't know if anyone did bottle feeding, but I can't seem to get Olivia off the bottle and to the sippy cup. She will drink other liquids in the sippy cup but not milk. And if she does it is only a ounce or two. I know they say if you wait to long they become more and more attached to it. We have finally got her out of the routine of having a bottle before bed. She now has a bath reads some books and then goes to bed. But a hour or two after she eats we give her a bottle, b/c she won't drink it for meals so it's the only time she will get any milk. If anyone has any advice please let me know. I have tried the changing the first bottle to a sippy cup, but she ends up not drinking any milk until I give her the botttle. I also tried putting water in the bottle, she drinks the water and never drinks the milk. It's so funny how motherhood is, once you get one thing down you have to move on to the next.
