Ben climbs everything...slides, shopping carts, couches, coffee tables you name it he climbs it! This means that I can't leave him alone for a second so when I need to use the washroom or run upstairs I put him in the highchair for a few moments and trust that he is safe there...until now! I came in the kitchen to find him standing up and rocking the back. I don't know how he managed to get out of the straps let alone the tray that was pushed up tight against him! What are we going to do with him now???
