We've been known to wake up with all five of us in the bed - plus the dog and occasionally the cat. We do have a king size. DD1 (8) and DS (6) love to snuggle up in one of their beds, but we only allow it on weekends or school holidays or the talk all night!! Miss P is now 16 months-ish and I am confident that she is too big now to be rolled on, she would wake up and complain loudly!
