3.4 should be okay to deliver naturally. I had a big baby too. Emma was born at 3.675kg. I did have a difficult delivery - laboured for 16 hours, baby was OP (facing up instead of down), had to delivery via forceps and I had a 4th degree tear. But at least I still went through the labour process naturally. If you don't want a C-section, then don't let your doctor talk you into one. After all, the ultrasound scan is just an estimate.
