S.S.
Try giving her milk in a cup with a straw even if you have to help her. My son was off the bottle at a year and on a straw and cup. She will get so she will drink her milk form a cup it just takes time because mostly she drinks juice and her water so it is different for her plus you didn't say does she get a bedtime bottle? that might be the different if the bottle is only milk at bedtime.
