My Grandson is six month old and whilst sleeping pretty well during the night 7:30pm to 02:30 then back until 05:00. During the day he fights sleeps, to the point of maybe 45 minutes of scream/crying. Despite giving us all his sleeps clues of eye rubbing, hair twisting, red eyes and yawning. if he does go down he will wake up anywhere between 20 to thirty minutes clearly not ready to be awake but can't/won't go back to sleep and so the crying begins again. i don't have any experience this to help my daughter. Can anyone suggest anything?
