Just something that ive found, i slept in oskars room when we moved him out of his moses basket into the cotbed, it was terrible, i was disturbing him and he was disturbing me, he would grunt and sometimes cry out for half a minute or so and i would be up straight away shushing him, i moved back into the bedroom and we just left both doors open, although I would still get up ridiculous amount of times to start with i actually only heard him when he was properly crying. My other half on the other hand heard every peep for the first few days and used to get up and run into the other room and by the time he got there oskar was actually settled himself! Hehe so he ended up getting up unnecessarily.
We are at grandparents at the moment and although the bedroom is big, even in good nights i wake up loads just because he makes noises in rhe night, last noght he cried for 30 seconds or so in his sleep and just webt back to sleep, he didnt need me but i woke up of course. I also found that until we achieved independent sleep during naps there was no chance of Oskar settling himself in the night. You LO just sounds so much like what we went through, although after recent illness we are tryin to get back on track.
