Breastfeeding past 1 and sippy cups/cups

My son will be 1 next month. He nurses a couple times over night, in the morning, and on demand when I’m home and at bedtime. Lately when I’m not here he’s been refusing the bottle or chucking it away when he’s only halfway through. Tried sippy cups, mini cup, 360 cup and he just treats it like a toy. He has enough wet diapers. Not sure how to transition from bottle to cup. We’ve been trialing different cups for awhile now. I’m planning to let him wean when he’s ready. So do I just keep my pump schedule exactly the same after 1 year? Just curious to other peoples schedules.
