How to get my 19 month old to switch from Soft Spout sippy cups to Hard top sippy cups?

My daughter has been on the soft spout sippie cups ever since she was 6 months old! And I have been trying to get to her to switch to the hard top sippie cups for about 3 months or more and she will not drink out of them!!! What to do??? I have tried the putting water in the soft spout sippie cups and kool-aid or tea or milk in the hard top kind and that doesn't work!!! She still won't drink from them!!! Its really stressing me out, I just wished she would change over (2) reasons (1) Those soft spout sippie cups are just aggravating to me and if u dont have them on a certain way, they leak (2) I'm afraid its going to mess her teeth up by still using this bottle like cup!!!! Please if anyone knows what I can do, I would so appreciate it! Oh and I have tried the straw cups too and she dont like those either!!!
