DD (age 5) fell asleep at 7.45pm this evening with me (9 months pregnant) conked out with her too. I got out of the bed at 8.30pm and she woke up.
She is still awake! I've had to swap with DH to deal with it but literally will not stay in bed and will not sleep.
I can't remember what this is like (although we're going to be reminded by DC2 soon), what can we do?
