Son got bit at daycare on his first day

My son started a new daycare today and When I arrived to pick him up no one mentioned this at all. When we got home and I was undressing my son. He said “mommy look at this” “him did that”. I said “who ? The baby ?” And he said yes.

This morning when I dropped him off (he’s 2yrs old) and was filling out paperwork there was baby in there about 1 yr old and the director took him by the hand and said come with me because you like to bite ppl. Which is why I asked if it was the baby. But he said yes with no hesitation.

My thing is that when I got there the director was on her way out but the owner was still there and she’s a Police Sargent. It was my first time meeting her. I only met the director before. But when I arrived she could have mentioned that so I wouldn’t be shocked when I got home to see because now all this stuff is going through my head. My son is very smart and speaks in sentences but he’s only 2 so I believe what he says but only to a certain extent. Omg... I will mention this tomorrow when I drop him off because I’m very concerned at why she didn’t care to mention this when I got there to pick him up. If this happens again he will not be going back there. It was his first day. What would you guys do?
