My very first day of daycare I had a 3 yr old girl, we had survived the park, but she was sitting on the bench while I was emptying out her shoe of sand and I have no clue how it happened but she kinda rolled a bit, scrunched into a ball and fell through the space between the back of the bench and the seat... hit her head on the pavement..... she was fine, and mom was fine, and later I found out that she had 2 left feet and was so clumsy that she would literally just be standing there and fall down!!
