How to stop co sleeping?

[Telller]

we don’t fully co sleep! DS is 7mo, he starts in his bed so from 7pm until about 1/2am he sleeps there.

from this point on he seems to be in a light sleep and takes so long to settle alone that I just give in and get him in our bed! But as he now sleeps on his front and spreads out - there’s no space for me and I have to get out of the bed (sleep on the floor) DH is in the bed too but I wouldn’t wake him to kick him out aha!

DH offers to do this btw but with him going out to work I feel bad and say no

so back to my point - is there any way to stop co sleeping? I do love being close to my son and when he snuggles me as he wakes up! But it’s just we don’t have the space 😭 if things weren’t tight (I’m on reduced pay now maternity leave and we’re saving to move home , potentially a renovation job!) I’d buy a super king bed but I just feel I can’t justify spending the money when we have a 1 year old perfect condition kingsize just because it gets cramped

He expects to go into your bed at 1-2am so for long-time peace you might need to try just soothing him in his room until he goes back to sleep. There are great books for this or have a look here for a method that suits you.

If you are not consistent and give in you will find yourself back to square one so stick with it.

If you don't want him in your bed, don't bring him in there! You'll have a couple of nights of crying and then he'll learn he can sleep in his cot.

Do you think something is maybe causing the lighter sleep, perhaps hunger, a drop in temperature, or if he's having a lot of sleep in the day, he might get to 1am and have pretty much had enough sleep for the night which is why he's needing so much input to stay asleep?
