my lo (51/2 months)doesn't usually eye rub until after 5pm. he will get a little fussy during an activity before rubbing or yawning. I have just been going up so that we start napping at 5pm (ie in chair with lights out and white noise on). Today we started at 4:30 (he woke at 2:45 from previous nap) nd he fell asleep within 10min , but then woke after 10min and wide awake.
