When the wife had our second, it turned into a very hasty home birth. The midwife that came to us did not have the timing so precise. She came through the front door (which I had left open) at the same time as the baby crowned. She just put her bag down and caught him as he came out. 10 seconds later and I would have had to delivery him myself. A couple of burly ambulance people waiting with me would have made me a lot more comfortable.
