Our baby is 4 months and we co-sleep most of the night. He has his day sleeps and first sleep of the night in the cot (next to our bed) and then at his first feed (around 2am) he comes into bed with us.

He generally self settles now. He will usually grunt and wriggle a bit as he's settling but if he cries we don't leave him. We usually stroke him and settle him back down then leave him again to self settle (he generally goes to sleep better without us there) but if he's having a hard time getting off we sometimes put him a baby carrier or cuddle him on the bed to help settle him off to sleep.
