Yep Dino, I've agreed with my Head that I'll go in for the first two TD days, no matter what (I'm running one of them), then if I don't feel up to actually doing a job in class, I'll go off sick. He's fine for me to do that, and the NQT guy we've got covering me is on call for that to happen too.
I just had an hour on the phone with my aunt, who has three children, giving me the full on run down of all of her labours/births. Then her daughter in laws labour/birth.
She was quite funny about saying when they put her first son onto her stomach, she looked at him and felt really strange - all she could see was her brother's face, and it felt almost incestuous or something. Weird.
