Ftm, btw cesarean and normal which one should i choose or consider?

My gynae told me my baby was considered big at 32 weeks - 2kg. Delivered via vaginal delivery and he weighs only 2.79kg at birth. But he was delivered early due to PPROM and I was in high risk and may have to do c-sect but end up with normal delivery. Don't trust the weigh but go with your guts. Don't decide too fast. I store his cord blood with public cord bank from KKH. Can't remember the name.
