We just used a cot with Aidyn from when he was born, although a lot of the time he was co-sleeping with us anyway.
I would have liked a bassinette, but we couldnt afford one at the time.
Next time I will probably get a cheap bassinette, that way its easier to have him in the room next to us.... or we could always just take one side off the cot and put it against our bed... I did this when Aidyn was older too.
