My 4 week old ds2 sleeps so amazingly well when cosleeping in my bed. Wakes up once for a quick feed, so ends up doing a couple of 4-5 hour stretches of sleep at night. On nights when I put him in his cot he wakes every couple of hours for a feed and sometimes it takes a couple of efforts to get him to settle in the cot (yes I know that is normal sleep behaviour for this age).
So I'm happy to keep cosleeping as I really cannot be bothered with the cot business and sleep deprivation etc BUT I'm worried that it could mean long term there could be different issues that are harder to break! Is this true?
So I'm wondering whether I'm better off suffering sleep deprivation but persevering with the cot

Just to add for background.
*Ds1 was an atrocious night time sleeper until he was 2.5 and ds2 sleeps so much better, both at night and day. I did try cosleeping with ds1 and it failed as he fed all night long. So the idea of long term sleep deprivation scares me perhaps more than other parents.
*I have a few complicated months of health issues/treatments coming up for myself so I do need sleep for my mental and physical health.
*Ds2 naps in his buggy, car seat and swing happily. Just doesn't seem to like the cot. Obviously he can't sleep in any of those over night.
So should I persevere with the cot as ds2 is being quite typical with his sleeping patterns in the cot (and I should stop expecting more) or should I just risk it and keep enjoying the sleep and peace and keep cosleeping?
