1. That my ex husband was an inconsiderate moron;
2. That I do better reading books and talking to experienced mothers than listening to a nullipara talking rubbish about how losing one's mucus plug is absolutely a sign of imminent labor.
3. That the emphasis on "PAIN" and "PAIN RELIEF" starts well before the first contraction is ever felt.

I bet you can tell that I was a real delight to have around in antenatal classes Maybe I just got the wrong ones!!
