Milk - sippy cup

My 19-month-old somehow put a hole in her straw in her regular milk sippy cup so I had to throw it out but I didn’t have a back up I have 1 million other sippy cups and she’s refusing to drink milk in it i try not to keep forcing drinking of the milk because when she does get her regular sippy cup back I don’t want her to have a bad association with milk but this morning she already didnt drink her usual 7 ounces if she goes a day without drinking milk a problem???? Im so frustrated
