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

My baby is growing bigger, at 30wk abt 1.9kg, so doc says that maybe i wont be able to deliver normal if baby growth goes on. I am going to book for hospital delivery soon , should i just book for cesarean 1st or what, i am confused as FTM. Will book at ME.Novena. and any mummy apply for cord blood banking would like to know more, as i might be applying for that.
