It is start from here, a peaceful normal horizontal ground, and when the kids come, all the thing will become different, with kids, here will be a wonderland.
In the kids' world, there are no boundaries, this is both for their behaviors and furniture. They can sit, lie down and crawl at the same time, and the floor can be a table.
Kids do not want to use the furniture as the way which adults use. And kids like ground.
