Breaking co-sleeping

My son will be 1 in 3 weeks and has slept in my bed with me since he was born. He was breastfed which is why we developed this habit as it was easier for me when it was time to feed in the middle of the night. I have 10 weeks left till I’m due with my second son and I want to break him from sleeping in my bed before it’s time for baby to come. Any helpful tips to make this an easy transition for us both.
