It is one of many daunting decisions parents face — allowing their children to share a bedroom.

Considering that many times siblings can barely get along in any room of the house, deciding to move them into a shared space is a choice fraught with challenges and risks but also tremendous potential rewards. Sure, your kids might stay up all night playing or they might turn their bedroom into a UFC-style fighting ring but there is also a chance it will turn them into even better friends and will teach them how to coexist with another person. 

Here are a few tips to help with the transition:

1. Discuss It

This is a decision that should be discussed at length for weeks or even months before becoming a reality. Even if your children are young they need to be aware of the pros and cons of sharing a room as well as the expectations of such a move. Everyone needs to have a voice in this process. Begin the conversation early and discuss it often.

2. Set Ground Rules

There are many questions to answer — what time is bed time? Is there a nightlight? Is the door left open or closed? What happens when one sibling falls asleep before the other? What happens when one sibling wakes up before the other? Try to plot out answers to these and other questions early in the process. That will encourage everyone to be on the same page and know what is expected.

3. Involve Them

Your children will be much more invested in the process of sharing a room if they are able to select their bedding, their decorations for the room or a color scheme that will make the room feel like their own. Give your kids some options or think of the things they both enjoy and tailor their choices to those items. If you allow your kids to be intimately involved in setting up the room, chances are they'll work harder to make the transition succeed.

4. The Room's Geography

Layout plays a crucial role in the success of siblings sharing a room. Are your kids going to sleep in bunk beds? If so, a major decision needs to be made regarding who gets the top bunk. If your kids are not using bunk beds, place their beds in specific spots in the room that will keep them apart and discourage jumping, horseplay or any other behavior you want to curb.

5. Cut Down on Toys

It might be a good idea to limit the amount of toys in the room your children are sharing. Experts say a bedroom should be used for sleeping and if you follow that advice, keeping toys to a minimum will give your children more chance to focus on rest and allow them fewer distractions to keep them up late at night. If you do have toys in their bedroom, try to make sure they are cleaned up and put away each night.

6. Trial run?

Enjoy camping? It might be a good idea to dig out a couple of sleeping bags and let your kids see what it would be like to share a room before the actual move occurs. This might be an opportunity to iron out any problems and to see what trouble spots arise.

7. Prepare for Bumps

There will be snags. Prepare for them. There might be nights of restless sleep or one child waking another inadvertently. Sleep patterns might shift. One child may not like giving up her privacy. All that you can do is to prepare yourself for any eventuality and try to make the best of the situation.

8. Assess the Results

Give the experiment a few days or weeks and keep a good line of communication with your children about sharing a room. Ask them how they feel about it and if there are any issues they're dealing with. Is there anything they'd want to change? If it's working, maybe there's a way to make it even better. If it's not, maybe it's time to find each child his own space.
