Sounds trivial but my ds (3) left his Elmer backpack and in it all his most precious cars from the film Cars. He absolutely loves them and is sobbing as we speak.
We lost them (or rather I am hoping left them) at church this morning. It was St Saviour's church W9 and it was the 11am service.
If anyone can help it will be much appreciated as I am as sad as him at the mo!
