Here is a video that Izaak took of sneaking into Elliot's bedroom in the middle of the night. Seriously it was after midnight. four and a half hours after she had gone to bed.
Unbeknownst to us (at least until the sneaking into her room with a video happened) she was awake 'doing her lessons' in bed with a notebook, a crayon, and a flashlight. She is three. She doesn' t have any lessons.
