Baby sleeps so much better when cosleeping so what are the long term issues if I keep soon this?

[SunnySaladDays]

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?

DH always complains her gets pushed out of bed because of DD.

I've checked and he usually has more bed space than I do (and he's thinner!!)
but, of course DD gets the most bed space, enjoying lying diagonally between the two of us, or at best, straight with legs and arms splayed out everywhere, in our ears, over our faces, across our bodies....

I can't stand anyone touching me while I'm sleeping so co sleeping was never going to be for me! Saying that I often fell asleep with dd on boob as I side fed at night in bed but always seemed to wake up an hour or so later then transferred her to bassinet next to bed. She never bothered with this transfer and didn't seem to want the comfort of the co sleeping, in fact if I try and bring her in bed with me in the morning for a snuggle (she's 19 months now) she hates it!
