DS2 has been a really good sleeper for a long time - 2hr nap in the morning, bed at 8pm and asleep straight away, through till nearly 7am.
It was lovely.
BUT the last couple of weeks he's been waking between 2-4am, calling for us and refusing to go back to sleep. He demands to get up, have breakfast, 'come in YOUR bed', anything he can think of and tells us he doesn't like the cot or his sleeping bag.
We are getting a bit desperate and don't know what to do - if we don't stay with him he yells and cries which is horrible, but also disturbs the neighbours and DS1 (5).
Any thoughts for what we can try?
