Once again Wade tried to climb up his shelves. They are taller than me and if the shelves were solid rather than supported by metal pins it would have tipped over on top of him. instead the shelves that he was standing on, and the ones below it just slid off the pins sending him and the toys to the floor. I can't stress enough how important it is to have safe shelving girls! You can't be everywhere and they WILL try to climb them, there's just no stopping them. So have wall unit shelving or ones on pins that will slide off. Don't just have a freestanding unit that's tall in their rooms.... it will crash down on them and could be tradgic!
