I was so worried about moving my second child into a room with the older sibling. I thought they’d just muck around and never go to sleep! While that did happen briefly, they now struggle to sleep in a room without the other. I also grew up sharing a room with my sister, so it’s all I know. So if you have a choice, are siblings better off in the same room? When is the right time to transition and is there an easy way to go about it?
