He's tired, really really tired, I'm so tired I'm screaming my head off tired.
But he's figured out how to haul up and cruise, so that's obviously more fun than lying down and sleeping.
So I am listening to him running around his cot screaming with tiredness. (well, I'm going in an out to him - he's not one for sleeping if anyone is around and until recently dropped off really well as long as he had his toy, dummy and blanket)
Any ideas?
