Cutting the bottle cold turkey at 1?

I know this HIGHLY depends on your baby, I’m not mom shaming those who are still going to use a bottle after 1 year. My son just doesn’t show interest in holding his own bottle and actually holds his own sippy cup. I’m also concerned about using the bottle too much after 1 for oral hygiene concerns, we started brushing his teeth already but I’ve read it’s best to go to a sippy cup to avoid hygiene problems. My sister is almost 7 and literally just stopped using a bottle at bed time (yikes😶) and I’d like to avoid that habit right now instead of a couple years from now when my son is more vocal haha. What’s your take on using a bottle after 1? If it doesn’t go well with using a sippy all the time should I bring the bottle back for bedtime? He doesn’t usually fall asleep with it, most of the time I feed him and then he falls asleep. We’re also still sleep training so I’m worried about introducing too many things at once. I’m probably just over thinking this lol. I’m also considering just doing sippy cup during the day for a couple weeks or so and then introducing it for night time. He does use a sippy through out the day for water and small amounts of orange juice (yes much aware he doesn’t need orange juice but I give it to him with his snack or breakfast after his milk).
