Someone told me when I was pg with DD#2 that driving fast over speed humps worked! and watching 3 Men and a baby (they may have updated to a better movie) eating spicy food and drinking raspberry leaf tea (I tried this towards the end of last pg, a nurse at school said 2 teabags at a time- got induced early so can't comment on if it works LOL) DH was keen on nipple stimulation and sex but at that stage I wasn't keen on either of those things!
