My two sons have shared a bathroom for years. My husband and I have decided to give them a bit of freedom and have them design it themselves. One of my sons asked us if it was a trick, and I said no. I designed the bathroom when we bought the house, but my sons are the only ones that use that bathroom. They were happy and went to look online for some Kids Shower Curtains. My husband wasn’t so sure that it was a good idea, but I told him it would be fine. Later my sons said they wanted to paint the bathroom walls black.
