With a previous C-section you probably get to see the consultant at the 20 week scan appointment to start discussing options for the next birth.
I had mine yesterday, and he was very supportive of my decision to go for a repeat section (and gave me a date, as I could show that I've done my homework and made an informed decision), but he would have been also supportive if I had wanted a VBAC, he just wanted to make sure that I've looked at all the options.
I guess what kind of care and level of support you get will differ from trust to trust, and from consultant to consultant, and midwife to midwife, so it's not really a NHS vs private sector experience, but a trust specific one, I guess.
I'm really happy with the care I've been receiving both when I had my daughter and in this pregnancy.
As for breastfeeding, my midwife recommended an antenatal breastfeeding workshop in my first pregnancy, and a support group and I'm very glad she did. I didn't feel pushed but felt that the decision was down to me, but it was good to get support when I needed it (especially with a slow weight gainer, for which my GP tried to push me to 'topping up' with formula).
