My DH took DD, age 3.7 to cinema this afternoon. She had a kids size sweet popcorn. DH said that after an hour in the cinema she started running up and down the stairs in the cinema. Then they walked into town, about half a mile, and she ran all the way. When they returned home she was hyper active - noticeably more active than usual and she is a very active child anyway.
She also chose tonight to stick a pea up her nose - first time she has ever tried anything like that (and A&E couldn't get it out, so she has to go to an ENT clinic on Mon).
Has anyone else noticed similar effects with cinema popcorn?
