Always waking in a bad mood

[singsong]

2 yr old ds has started to wake up in an awful mood. He sleeps ok through the night but come the morning he wakes up screaming, shouting and being very angry with everyone and everything. This nightmare behaviour then lasts about 2 hours after which he returns to his normal happy self. The whole process then repeats after his afternoon nap. Have tried giving him cuddles and attention but he wont calm down any quicker so then I tried ignoring him and carrying on with something else to see if he would get fed up of screaming but no luck. Anyone else have a grumpy waker? Anyone found a way to make them snap out of it quickly?

My ds (2.9) is exactly the same. He's not as bad first thing in the mornings but is horrendous after his nap. I've tried everything I can think of (cuddles, treats/bribery, getting cross, ignoring) and it doesn't make a jot of difference to how long it lasts or how bad he is. I have finally come to the conclusion that he is just a very bad waker-upper(!) and I just leave him to it. I chat and treat him as if he's not doing it and let him come round in his own time. He's been like it since he was about 18 months but the episodes are getting shorter and shorter. At the beginning he'd go on for a couple of hours but at the moment he's down to about 5 - 10 mins then he's fine so they do improve!!

I did find it easier to cope with once I stopped trying to make it better and accepted that he would be in that mood when he woke up.
