You know what, that silly ob was just covering his own arse by sending that letter, in the off-chance that something does happen, which is very unlikely anyway! I have booked into a hospital, but am having a home vbac and the ob sent a letter to my gp and midwife saying he doesn't recommend it, it is dangerous blah blah blah, (because of course I hadn't looked into it carefully?), it is just so you can't sue them if something happens that they mentioned may be a possibility. But is still less of a possibility than ending up with another c/s because they can't keep their noses out!
Don't give the weight thing another thought, womens bodies were designed to birth our babies. The hospital cannot do anything that you don't give permission too, so you go in there knowing what you want and don't let them bully you. Have you got an advocate, something that can speak on your behalf if you are unable??? Make sure you tell whoever is going in with you what you do and don't want.
You can have a vbac. If the ob wants to be negative that is his problem but trust your body and your decisions!!!
Good Luck, stick up for yourself and your bub!
My decision to have a home birth, while a really really hard one, was to avoid all the unnecessary stress that you are being put through now. A vbac is just a birth, but for some reason we are treated like crazy, unrealistic women, just because we want a safer outcome for our baby and ourselves.
