Thanks everyone.

Clover - my kids are normally like yours. They can be either dead on their feet or sick as dogs but still want to go to school, so this is a big about face for them.

I picked DD1 up at noon today (normally a 3pm finish). She and I had a lovely afternoon of lunch, buying her a new winter outfit, having afternoon tea and just wandering before going to pick up DD2 from kindy. She seems to have perked up lots so maybe she just needed a bit of one on one time.

Will see what tomorrow morning brings but thanks for confirming its right to keep sending them. That's what the practical, logical side of me says but the hormonal, emotional pregnant whale just wants to hug them all day long.
