Has anyone got any advice on nightmares? my 2 year old has been waking up screaming (a horrid hysterical scream) normally around one hour after going to bed and then it can be as much as 10 minutes apart for the next hour and then 2 or 3 times during the night. It's completely exhausting and i'm not even sure that she's awake when she's screaming but does seem very frightened. What could it be? it doesn't seem to bare any relation to what she's' had for dinner and it's showing no sign of stopping. We leave her door open, landing light etc but she still is so unsettled. Poor love is completely exhausted and hasn't slept properly for weeks - know the feeling!!!
