Thanks so much ladies. It does help to know that others are seeing similar behaviour. Though I guess my gut tells me it's something more as he's gone from his standard level of screamy-no-no (which is still pretty full on compared to anything DD ever did), to just being out of control miserable from dawn to dusk.

During a nice big open mouthed wail today I managed to get a good look in his mouth and yes, there's the top of one of his bottom molars poking through. Ouuuuch. So with a dose of panadol on board and lots of positive attention from me this arvo, he's been quite good. Still refused to get his shoes put on, contradicted about half of what I said and fell apart when not allowed to bring a large stick into the house... but that's just normal!

Mmmm 2 is fun
