Hi Mumma
I say go for it.
But it sounds to me like the hospitals you went to are not too keen on the idea.
It could be a good idea to put a birth plan together so that they are in no doubt what you want. It may also be a good idea to have a support person with you who is willing to speak for you if needed during your labour.
If you want I could look for some research on this so that you have some information to show how safe a VBAC2 is in relationship to C/S 3.
