Hi my nearly 3yo ds has always been a great sleeper (not bragging my other ds was an awful sleeper) . He's been waking up for the late month around 3am talking and laughing loudly I have to go in and say you need to seep it's the middle of the night. Something knew it works sometime it doesn't.
He's dropped his afternoon 1 hour nap goes to bed at 7 . Nothing in his bedtime routine has changed nothing in his life has changed apart from Xmas coming up. Any ideas what I can do?
