Everyone bangs on about safe co-sleeping, but do people who co-sleep actually always do it safely? I know several families who sleep with their infants, they all tell you they stick to the Lullaby Trust guidelines, but I've on multiple occasions had evenings with them smoking and drinking and then getting into bed with their babies. Obviously this isn't an indication of everyone, but do people who co-sleep really follow every single one of the guidelines every single night?
