When you have 9 children people can't fathom how we can all fit into one house. First, there's a confused look on their face. Then it turns into a look of amazement. They become mesmerized when we say that the children share rooms and 9 children can share 3 different rooms. It's not an even split, but the arrangement we have works well for the time being. We have 4 boys and they all share a room.
My Lutheran Stud is quite talented. If I see something on Pinterest, more often than not, he can make it happen. We decided that making lofted beds for the children would give them a little more space. Our littlest girls share the smallest room. Thankfully, they all still fit on a toddler sized mattress. Our foster children have never had their own beds before. We found their beds on Craigslist and they were elated to when we told them they get to have their own beds.
Our oldest 2 girls share the last room. They're in the tween stage and enjoy hanging out in their room while the other children are usually playing together in other areas of our home. Most of the children's toys can be found in our basement, so a lot of their time is spent in the basement.
