I don't know if this helps.......but we started partially cosleeping when DS was about 8 months. DH complained about it for about the next year, and slept in the spare room just so he could sleep a lot of the time! (Fine by me, we had more room in the bed without him ). It didn't really cause problems for us, was just a niggling thing that went on. I wasn't giving it up, I was too tired without cosleeping. He now ADORES sleeping with the kids, he's a massive fan! So much so, that even though DS mostly sleeps in his own bed (shock horror LOL), DH wants to go and get him every night and bring him into out bed. Hang in there hun, it could just get better and easier
ETA I don't actually let him go and get DS1, I'm quite happy for him to sleep in his own bed LOL!
