DD1 is 3.2yo and has never been a great sleeper. She's never slept through the night and in the past has suffered from night terrors (thankfully over now), nightmares and sleep-talking.
For the last few days she's been saying she can't sleep because she has 'colours in her eyes'. She doesn't mean dreams, she knows what those are. She is completely healthy and doesn't seem to be in pain so I'm not excessively worried and she's not been sleeping any worse than she normally does. I've asked her if she's been rubbing her eyes but I haven't had a definite answer either way. Does anyone have any ideas what it could be?
