is the yummiest! We have our bed against a wall and have baby sleeping nearest the wall then me then sometimes DS1 (if hes sick etc, otherwise he sleeps in a cot at the end of our bed) then DH. Sometimes baby is between myself and DH.
Over here everybody co-sleeps (but most familys only have 1 baby) I think its a great way to build a nice bond with your kids and its so yummy all suggled together on a stormy night. Also if you have a baby with health issues you can keep a better eye on them and as somebody said here, if they stop breathing/choak/etc you do wake up.
