I rarely let the kids sleep in our bed. If my husband is gone on a trip, occasionally my daughter has asked to sleep in my bed but I can count on one hand the time she has. They are much more comfortable in their own rooms.
A month or so ago, my son unfortunately watched a movie that scared him quite badly. He normally stays in his room but this particular evening, he got up in the middle of the night and asked to sleep with us. Between my night sweats, tossing and turning and my husband's snoring and chewing, he lasted about an hour before whispering that he was going back to his own room...
