I used a cot straight up with my first and an anti-roll thingo but it was winter at the time and was just sooo cold to get out and feed him I even resorted to useing the basinnet section of my pram next to my bed With my second I went out and bought a bassinet brand new, DD was in it for 5/6 months it was fantastic although not really necessary it was a great luxury item iykwim? I think it's paid it's self off as I'll be using it again this time around right next to my bed

You can sometimes pick up a bargain bassinet on Ebay or baby sales etc I only paid $80 for mine without the stand and that was new so I don't think it's that much of an expence
