This is something I really really worry about when I have to give birth. I don't know much about tearing, only that it sounds painful! I don't know what the different degree tears mean etc. If you do what the midwife says and blow/pant when they tell can you still get a tear? What causes it? Is it simply the exit being too small for the baby's head? I had heard if baby comes too quickly it can cause it as well, is that true? I am considering doing this perineal massage thing I have heard about, does anyone have any experience of it?
