I need some help/advice.

I have an almost 12 month old..

I have been exclusively breastfeeding him since day 1 and have been a stay at home mom with him and have never been without him therefore he’s never taken a bottle.

He eats to fall asleep , and we co sleep.. was this our plan to co sleep.. no, but it is what’s worked out for me my husband and baby to get the best sleep. Now my question is.. how will I ever transition him out of breastfeeding when that time comes and how will I get him to drop the night time “feeds” when they really are just him pacifying to sleep. That way we can get him sleeping in his own space.

Thank you, I know everyone may not agree on how we do things but that’s ok, looking for advice from the ones with similar experience :)
