my ds was a great sleeper until recently..but now he wakes somewhere between 2am and 3am as if it is the morning - happy as flipping larry! - and is awake and indignant that no one else is up for the next couple of hours. he has a dummy which used to settle him, i have tried giving him milk (which he takes) but cannot work out what is going on. Of course it could be teething, but he doesn't seem at all distressed! Any ideas? Kind of hoping someone will tell me it will pass
