Hi S., my husband and I happily co-sleep with our 22 month old and co-slept with his older brother until he was almost three. When I was a few months from my due date, we knew we needed to get our first son used to sleeping in his own bed because once the baby was born, there would not be room for him. We wanted to start the process well before the baby came so he wouldn't feel displaced. He needed someone to lay down with him until he went to sleep and more often than not my husband fell asleep in his room, which I didn't like much. We ended up having him sleep on a crib mattress on the floor of our room for a long time. At about four he moved to his own room permanently. He likes it when someone can lay down with him but doesn't require it to go to sleep. I don't think that any point in this process was "hard" on him. I think you will get more sleep if keep your baby in your bed at least until he no longer needs a mid-night feeding. I love waking up next to my little guy. Happy snuggling!
