TIFU by throwing away a child's teddy bear and having to dumpster dive

I work at a daycare. Yesterday we were cleaning up after closing and one of the moms came back and said her toddler son brought a stuffed animal but didn't come with it. They're not really supposed to bring their own toys but of course my supervisor asks us to look for it. And I realize I actually saw the bear but I assumed it was the center's, and because of safety part of our cleanup routine is to toss toys if they're worn out.. so you see where this is going. It was really bad timing, we literally just brought bags to the dumpster.

She not happy and pretty much insisted we go look for it anyway. I felt bad for her but that was too much. My supervisor said it was up to me if I wanted to but I felt like I couldn't really say no because it was kind of my fault. Needless to say I'm glad I have today off...

TL;DR: I threw away a toy by mistake and ended up having to go through the daycare trash.
