Bruises after daycare

UPDATE**

Thank you for your input everyone! I called them last night and told them. They said they will look into it and definitely were concerned. They called the teacher and they said he fell on a toy. And when I dropped my son off this morning, they let me watch the cameras and he did in fact fall really badly (he climbed up the toy house and fell on his butt onto a plastic toy car 😫). They forgot to file it as an incident report. But we’re very apologetic. My son has been there a little over a year since he was an infant and they have been nothing less than amazing, so I do trust that this was an oversight.

I still notified his pediatrician last night and sent a pic so regardless it I documented. The daycare also has a timestamped pic in his file.

My son didn’t have these when I dropped him off. Should I be concerned?

That’s his inner thigh..
