Sam co-slept with us for many months then went to a crib right next to me then a little after a year old was in her own room.

In the beginning sleep was better for me with her in my bed (we used a thing to put in an adult bed that has breathable "walls" that help protect from our pillows). When she got bigger and didn't stay swaddled she was kicking me in her sleep (only me never dad) so into her crib she went. At some point she started trying to play or have our attention if she woke up so into her own room she went and peacefully she has slept thru every night since. Even when she is sick she still sleeps fairly well, falling right back to sleep after receiving care.

So I guess I just went with the flow of what worked and now we are expecting baby #2 so my plan is to do the same but I guess that could change if the baby has a different plan! I don't know if I'm ready for round the clock feeding again but I'm up anyway now with hip pain so I guess the sleeplessness has already started.
