thanks for all your replies.
He has only ever got up to DD about half a dozen times in her life, and i can't see it being any different this time around. I have done my fair share of co-sleeping with DD, where we fed laying down, DH has ended up on the lounge these nights as he doesnt believe in co-sleeping, i just thought i might get some good tips to avoid the whole scene between DH and I, arguing over him going to the lounge, bub in our room/bed whatever the case may be at the time. like i said, probably just overthinking it all really, i have told him i'm doing whatever it takes to get a reasonable amount of sleep as i will have 2 now, and will still have to be a responsible parent for DD1 all day while hes at work, and i guess in the end i will just do what it takes, and if he doesnt like it/agree with what im doing, he will just have to find the lounge again, or i will have to invest in a bed that i can use myself.
I was just interested to know what others did when bubs was in their room, to minimise the disruption to their partners and in turn prevent arguments.
