Holy grail transitional cup?

My 15 month old drinks water from all kinds of cups, but will only take milk from a bottle. We have tried so many different cups but she screams and pushes them away. Yes, she gets plenty of dairy so we could not offer milk at all, but she screams for it before bed.

Help me out, moms! I’m delusional and believe the next cup will finally be the one.

Thanks in advance!
