DS is 3, and has been waking up between 1-3am, wide awake and wont go back to sleep. He turns all the lights on between our room and his and runs throught the house screaming until we wake up. He wants to sleep in our bed, then he wants to sleep in his bed, then he wants a story, leave the light on mummy, stay here for a little while mummy.

I was getting more sleep than this when he was a newborn, last night I got 2 lots of 2 hours and now Im at work trying to figure out whether I've got enough sick leave to go home early and sleep

I dont know what to do. Family members think they are giving advice, but drugging him with paadol and hoping he will sleep through is just not on as far as im concerned.
DH will happily roll over and ignore it all and let him scream, either that or he'll scream back at him and scare him half to death - neither of which Im happy with.

I know it will take a while to get him back to his regular sleeping pattern, but i dont even know where to start!

Could it be related to me being pregnant? Or is it normal for a 3 year old?

I've asked him if he is having bad dreams and 90% of the time he says no, no bad dreams, nothing hurts, he donest know why he is awake.

Help!
