Unfortunate but true, you have to be careful when dealing with the little ones as they learn how to walk, run or even just lift their little heads. my now 16 year old when she was in 4th grade at meet your teacher chipped her front tooth on the head of a friends kid who was 2 years old and came running down the school hallway to greet her but tripped over her own feet at the last minute. Ooops--chipped tooth.
