Lol at E falling asleep mid tantrum! I've never seen that before! Jack will drop off if he's tired (lily never has), and he's done it mid play, but never mid tantrum!
I'm just lying in bed listening to J chatting, after a short night. He'll be grumpy by the time the sun comes up cos he woke early today. Can't think of any reason for it except he had a very very low key day yesterday with very little exercise. I don't do much to compensate - I think once they've dropped their naps it's easiest just to keep a set BT and let them self regulate. We're travelling today and away for the weekend in a strange house, so I'll probably put J to bed slightly early tonight to account for the early start, and also to give him time to settle into a different bed, but I can't go too early cos he'll wake up early again tomorrow, so generally I stick to a set BT now.
