Whoops! DS, who is only 3. Found some small/ stocking bits I had hidden in one of the filing cabinet drawers.
He got out a little fire engine so I let him open it. I then got him out of the office and distracted, he didn't mention going back in. I'll obviously move everything now. I don't think he will remember what other things were in there, but he will know he got a toy from that drawer.
He won't link it on Christmas day will he? He is pretty sharp but is still a 3yr old
