Hi sweets,
I think you dont have to justify your decision to anyone, if its a VBAC you want, then no one should stand in your way. Your
DH is supportive of your decision and he will be there to support you during the labour so dont worry too much about everyone else. Just tell them this is what you are doing and that your not really open to further discussion about it. Your baby, your body, your choice.
Best of of luck, hope you get that vbac xx
