Help engage head/induce labour

This is my second pregnancy. My first resulted in induction and emergency c-section at 42 weeks. Although it was ok, I would like to go into natural Labour to be able to care for my daughter.

I have started:

- using a birth ball

- drinking raspberry leaf tea

- fast walking for 30 mins a day ( when I say fast, I mean as fast as I can)

What are you going to try? I'd be interested to see what else is out there?
