I think babies are safest when sleeping near their parents SIDS guidelines state this too, to keep baby close to you ie in your room for the first 6mths or so.

We had DD in our room with us for the first 4mths and you get used to hearing their little noises in the night too and it's reassuring they are breathing! I couldn't have imagined having DD anywhere else but with us! Mind you its exhausting getting up and having to walk to their room to feed them too!!!
After 4mths she went to her own room as she slept better in her own room as DH's snoring would wake her up! Then 9mths of age she came back in and co-slept with us from then on.....

I think it's one of those things you will just work out when bub arrives.
