We’ve watched Frozen so many times that I’m constantly singing Let It Go. Last night I came across a short clip preview of Disney’s newest animated short film Frozen Fever. I played it for Em and she lit up like a Christmas tree. “Anna’s cake-cake” she shouted over and over. “I want to see it again, I want to see it again” and “again, again, again” was all she kept saying. And so it went on replay, again and again and again.
