Sippy Cup?

I feel so naive. FTM here and I just saw on a different post about when to introduce a Sippy cup and a lot of moms said around 6 months. My DD is 5.5 months and EBF (she doesn't even take a bottle) and the thought of a Sippy cup hasnt even crossed my mind! I'm not sure how I feel about giving her water, and I definitely don't want to give her juice yet, but I also read about separating the association between breastmilk = breasts and other liquid = Sippy cup. What have you ladies done?!?! And how often do you let your LO drink from it, especially if you do breastfeed?
