If baby settles and sleeps well enough in a cot then I don't think there's anything wrong. I put dd in a bassinet originally but after 3 weeks of no sleep tried her in the cot and she slept for 5hrs straight, so I think some bubs like the closeness of a bassinet and some prefer a bit more space. I'll be trying this bub in the bassinet but only coz I want to try get my money's worth out of it lol
