DD has always slept in our room. She was in her bassinett at first but would often be in our bed to help her reflux. She would only sleep on her tummy and it felt safer to do that in our bed rather than in her own. I know it goes against all guidelines, but it felt right for us. She did go back to her bassinett when things settled down around 3-4 months. But at around 6 months something changed and we gave up trying to get her to sleep in her cot (which we even moved into our room). We now happily co-sleep and every morning DH asks me how our night was.

Personally, if DH gets disturbed, too bad. It's called parenthood.
