Hi Solosola,
Welcome to the forum. I just noticed that you are a medical doctor. None of us here is a doctor, except for one member who treated for HCV but doesn't come around much and another who is a scientist (HR, who also doesn't come around much).
As Bill said, there's about a five percent chance of vertical transmission but I don't know if the risk is greater through c-section or vaginal birth, although I would guess the former. I'm quite sure breastfeeding poses no problem, as HCV is strictly via blood-to-blood contact.
Anyone with HCV should be immunized for HBV and HAV, if no antibodies for these are present.
Studies are limited in pediatric hepatology. You can have a look at this thread, which concerns a new member discussing the tx of her eight-year old son:
