Non-leaking sippy cup

Does anyone have any recommendations for a sippy cup that doesn’t leak when tipped over or dropped?

My baby is 8 months and is breastfed (don’t use bottles). I am going to start letting him use something to drink from during the day because he doesn’t seem interested in nursing unless going to sleep. I want to start using the cups for pumped milk and feel he is too old to get him used to bottles (plus he’s not really interested in those either).

So non-leaking baby friendly sippy cup 😊

Thank you! 😁
