As a mother of 3 almost grown boys, that worked in a day care environment for 12 years, I feel like I need to share my opinion here. Accidents happen. Even in a 1-1 environment. He could have simply tripped and fell and his teacher not thought anything about it. In a busy environment, even as a mom, sometimes you just pick them up look for blood and send them on their way. My son has a friend that was simply walking across the yard tripped and fell and that fall broke his arm. Don't get me wrong, that first broken bone can be pretty traumatic, usually more for the parents than the child. Your ortho specials should be able to give you some idea of how the bone was broken by the type of break. Good luck. I hope God heals him quickly and gives you peace about the matter.
