You could get a cradle!
Typically bigger than a bassinet especially if you buy certain brands like Boori, Gro Years and there are a few others and 'I' prefer them looks wise as they are not so frilly.
We had one with DD1 and bought another when we had DS1 as we liked them and we had one in his room and one for our room. We always planned to have four kids so, although they are only in them for 6-9 months we could justify buying them.
DD1 was only in it for 6mths, DS1 was in it for 8 months, DD2 was in it for 10.5 months as she was a really bad sleeper and her room is at the other end of our house so we pushed it a little. DS2 is still in them and will be for atleast another 5 months as he will be sharing a room with DD2. So, overall our kids will have been sleeping in them for 2.5 yrs. My point is it depends on how many kids you have and if they are good or bad sleepers etc.
Even if we only had one child we would probably still buy one as 'I feel' a newborn just looks so lost in a cot and cradles and bassinets are so much more snug for them!
