I defianetly think emotions and your mind have a lot to do with it... I was stressing about going into labour and not being able to say goodbye to my granddad, or going into labour when we were staying with my parents (and away from our hospital).

I found out my granddad passed at about 4pm, by 8pm I was on the phone with the hospital letting them know I was havinf irregular contractions and midnight my waters broke. I definitely think in a way my mindset was stopping me going into labour, and once my granddad had passed I felt a real release, that it was over and he was at peace, and I went into labour.
