Advice?

For night time feedings (usually about 3-4 of them) I feed my son either side lying or in a reclined position and half of the time we both end up falling asleep like that. That means we end up co sleeping and I know that’s not the safest thing. How do you mamas handle the night feedings? How do you survive them? I already feel tired all the time, I can’t imagine how tired I would be if I stayed awake for his entire feeding. I’m debating about putting a rocking chair in the bedroom so I can nurse him in that without falling asleep but again, I’m worried I’ll end up exhausted. he is a pretty light sleeper and falls asleep while nursing so moving him from the boob to his crib is a trial.
