Thank you all for some wonderful information. It's nice to know that if things don't go to "plan" then I still have options open to me and won't be forced into anything that isn't necessary.

The good thing is that I'm not scared at all to deliver at home. DD's birth showed me that I'm able to deliver a baby solo
If you DO find yourself in this situation where you're labouring quickly and get to crowning very quickly, work on your breathing to slow you down - deep and slow. There is no need to even 'push' if you're having a quick labour, because your uterus will be doing all that work for you, pulling up the cervix and helping you open out - you could birth your baby whilst unconscious! One way to minimise risk of tearing and PPH is to reach your hand down to your vagina to feel the baby coming, and to guide its head out, almost holding it in.
This was how DD's birth was. I went from 3 to 10 cm in less than half an hour, and only pushed for 7 minutes. I was on my knees on the bed and when the midwife went to help guide the baby she found my hand was already there and backed off and told me I could do it myself. I actually nearly laughed during the pushing stage because I could hear the midwife saying "great push, now another little one just like that one" and I knew that I hadn't even been actively pushing and that it was my uterus contractions doing all the work, lol. I don't even remember feeling any pain once I was pushing. Once her head was out I felt her turn in my tummy, then I reached under her arms and pulled her onto my tummy. It was magical. Seven minutes later I delivered the placenta and a couple of minutes after that my Ob arrived. I told him he "you missed the party, but you're welcome to stay for the after-party", haha. He never even had to put gloves on because I had no tearing or grazing. I didn't with DS either even though they are not small babies (DS was 8lb10oz and DD was 8lb3oz).

I'm really looking forward to this next birth, but I'm a bit of a control-freak and like to know the "what-if's" and have this planned as much as possible

Feeb, that's a gorgoeus offer honey! I'll certainly remember to keep your number in my phone! Lol, well it's not as if I was planning on deleting it anyway
Oh and yes, I will definitely be declining a trip to Sunshine hospital if that's where the ambo's would like to take me. I doubt they would want to take a little side trip all the way to Freemason's in the city, lol.

I guess when ambo's are called out to births they generally get there to find a bit of panic and chaos, so I could certainly understand if their first instinct is to try to come in and sort of take over. I just hope that if it comes to this situation, the ambo's that arrive are able to see that things are calm and going well, because of course I'm assuming they will be
