Best sippy cup for breastfed 6 month old

CL

My 6 month old isn’t drinking water.

She’s breastfed, has no dummy and hasn’t took a bottle since she was 2 months old.

She’s started solids but I can’t get her to drink water.

We have the munchkin miracle 360 cup and I’ve tried this as well as just a cup and I can’t get her to sip the water.

Any recommendations?
