When I was in college, I was taught to never have your back to a child. You are always to have eyes on anything that went on in a room. I live by that always! I see everything and if I'm not able to I make sure my assistants never have their back to any child as well. I teach that age so you constantly have to have your eyes open. These children are so small and some don't even speak so of course they are going to cry to try and get what they want. They are very young toddlers. I feel like throwing up just thinking about that incident.
