firstly you should not feel bad or daunted about telling your mum you are having a c/s...she has had her birth experiences and it is not for anyone to put their wishes or expectations upon you
I agree with Natalie on that one.

Maybe if you tell her the situation with the baby she might understand better. Although even if you bub is IUGR you could still have a VBAC. My dd was 3lb 3oz birthed naturally @ 31 weeks and coped really well. I was prepared for a C/S by one OB then another said that I could have a SVD- I thought all prem bub were born via C/S but the 2nd OB told me that even though they are small this (vb) is what every baby is "designed for" and are able to cope with.

I hope everything goes well for you.
