Hi Shazza, it's a valid concern that you do have considering the size of your last bub. The benefits to bub of having gone through some labour first is that it will help prepare then for life in this bad old world by clearing all the muck out of their lungs and getting them ready for oxygen when they take their first breath. Some babies born via c/s suffer from respiratory disorders and may need resusitating or oxygen therapy at birth and oxygen for a few hours afterwards. But that may not be an issue at all - just saying that it can happen.

I would also consider the 'afterwards' of a c/s too - you will have 5 children that will need looking after and you wont be able to drive a car for at least 6wks. Not taking into account how well your recovery is too in regards to infection and wound healing. Unless you have great family support to help you through that then it's going to be really difficult to manage on your own

personally I would go for the vaginal birth, because shoulder dystocia (I assume thats how your last baby got stuck?) is a positional problem as opposed to a size problem most of the time - you did get her out in the end so that oughta count for something? Even if this baby is this size again, or larger, you need to equip yourself with the tools to birth a large baby - check our www.spinningbabies.com for some tips on this.

Good luck in deciding and if you have an other questions or just need support, then please don't hesitate to ask.
