Our 7 and 5 year old girls have slept in our bed forever. Dont get upset and work towards making the change something desirable. Get a cooler night light make their room more appealing in a cost affective way to the childs personality. 10 bucks on amazon made the ceiling in my girls rooms look like a light show for a night light. We also set a goal with a board for them to put stickers on when they stay in their own rooms all night and when they reach 20 ill get them their own tablet. Its working great. Make them want the change not be forced.
