We put DS into a bassinet on wheels, and had him in the family room thru the day, and our bedroom at night til he was 4 months old!!! I wanted to keep him in the bedroom next to me for as long as i could. Then once he turned 4 months i had to move him into the cot in his bedroom. I missed him!
I do think they feel more secure in the bassinet, as it is a similar size to the hospital crib.
