How to transfer a very clingy baby to crib?!

Ashley • Wife👰🏻Boy Mom💙💙 baby #3 brewing👶🏻

So my 8 month old son is soooo clingy, which is totally my fault cause I’ve been co-sleeping with him since he was just a few weeks old till now! But it’s getting to the point that it’s not very enjoyable to co-sleep anymore cause he takes up the whole bed and it would be nice to transfer him to the crib so I can start getting some time to myself and to get stuff done around the house! But idk where to even begin!!! TIPS PLEASE
