My 16 month old DS is fine going to sleep, sleeps through the night... but then wakes every morning and wails and screams, getting worked up into a real state even if we go in quite quickly. It's particularly a problem if he wakes up early - sometimes we can shush him back to sleep and sometimes he won't go back to sleep or wakes up 10 minutes later and cries again.
What we're not sure is whether it's linked to a bad cough he's had for a long time or whether getting upset in the morning is something that can happen unrelated to this. He does cheer up once he's had some milk, so I suppose it might be hunger, but it does seem very dramatic for that. Has anyone else's DC done this?
