Hi oranges, have only read your OP as I need to dash!
A friend of mine had a 3rd degree with DC1, then 2nd degree with DC2. Vaginal, obviously.
Another friend had 3rd degree with DC1 and then I think no more than 1st degree with DC2.
I had 3rd degree with DC1 and am planning a homebirth for DC2. Also a friend has given me access to midwives' medical papers (I need to search through the website first to find the relevant articles) so that I can do further research. If you like I'm more than happy to share the info with me - just CAT me and let me know when you're due so I don't leave it too late for you!
IMO the key is knowing why you tore the first time round - I believe there were specific, avoidable causes of my first tear (including giving birth sitting down - terrible, terrible position for mother and baby), which is why I have total confidence in my ability to have a homebirth.
Finally, don't let medics put you off having a vaginal birth - medically speaking, having had a major tear the first time around does not guarantee that you'll have a bad tear subsequently. Usually (I have this on good advice) when medics try to put you off things that are actually not a problem, it means that they just don't have experience in that area. So why the hell don't they refer you to someone that does ?? Patient's best interests and all that. Anyway I'm glad you have two different opinions from your mws.
You need to be allowed to give birth 'gently' - i.e. allowing your vaginal muscle reflexes to push the baby out spontaneously. Picture it - when you push/ bear down, you are straining the muscles and putting them under enormous pressure. If, while this is happening, your baby passes along this tensed-up birth canal, it is quite obvious why you'd be more likely to tear than if you are not straining but allowing your body to do what it knows best. This is why giving birth on your back/ bum is so awful - it massively limits your body's ability to push the baby out spontaneously.
Ultimately, if there are serious problems, you should obviously do whatever is necessary to protect you and your child. But bear in mind things like (in my case) the fact that being on your back cuts the blood supply to the womb, which can create distress in the infant. Then they tell you 'the baby's in distress, you need to push'. And hey, presto! Tear. What I should have said was: 'In distress, eh? Fine, let me get off my arse and labour properly, then check the baby's heart rate and see if it improves'.
Also IME if you end up having an OB in the room they will get the baby out, no question, but they will expedite a swift birth rather than doing things in a way that will benefit your body as well as the baby.
Oh, how I'd love to see my (male) OB and the (male) dickhead who stitched me up cope with 9 months of pain and 18 months of screwed-up insides following a 3rd degree tear. Might give them pause for thought next time they're in a birthing room.
Anyway, please excuse my bitter ramblings! Ignore the bile and read all the other stuff! Good luck - and do get in touch about those midwives' documents if you're interested.
Oh, and there's a fab mw on MN (but sorry, I've forgotten her name!) - you could start a thread asking for mws to give you advice.
(bitterness evaporated now)
