Okay, so you didn't know it was a mystery but still. I couldn't really figure out where Samuel learned "uh oh" because we really don't say it much. But as we were leaving daycare he said and I asked if he says that all day. And she said, they all do. Grace (who I think Samuel has a crush on) pushes her cup off the table daily while saying "uh oh". I actually got all 5 babies saying it as I was leaving. Pretty funny, but I felt sorry for his afternoon teacher.
