We are co-sleeping with my 4 month old in a superkingsize bed. I have a bedrail on my side. When we go to Center Parcs in early January, we will be in just a regular double bed. That will seem cramped for just dh and me, let alone having a baby in with us. Also, I am travelling by train and do not want to take the bedrail if I can help it. So, how on earth will we manage???
