I'd gone upstairs and George gurgled at the bottom of the stairs and crawled back into the front room where DH was. Next thing I know I can hear George gurgling and babbling but very much louder! I opened the bedroom door to find him at the top of the stairs! I shouted my DH and asked if he had brought him up and left him there to which I got a 'No'.
Stair gate at the ready I think!
