I thought this was a wonderful idea for a baby activity for Bee. My first thought was that it would be a lot of fun to put a floor length mirror on it's side so that when she starts crawling she can watch herself. I don't have a floor length mirror, but I did pull the mirror off of the wall for her to play with for a while. She loved it!
Of course, Gracie had to join in the fun. Her presence just made the activity much more fun for Brianna. They interacted with each other in person and in reflection!
