I read that cosleeping is now also what some people call having the baby in the same room, and then bedsharing is having them in bed with you. Over here, in the US, I've actually never heard them called different things...well I mean cosleeping is always referring to them being in the bed with you and then you just say they sleep in your room if that's the case. So when I say cosleeping I mean actually in the bed with you.
