Can I kick-start the labour?
No, not really. It is the baby who decides when it is time. Research shows that the length of pregnancy is programmed in the genes, so it is something that the baby inherits from you and the father.
There are those who try spicy food, sex, going up the stairs or castor oil, but mostly with dubious results.
The best solution is to wait, which is not the easiest thing to do as you move towards 42 weeks and you start wondering if there is ever going to be a child or if you just imagined it. The most common advice is that if it feels too slow, try to do something every day - movie, coffee with friends, dinners and such like.
