Naughty, as chris have explained, twins tend to born earlier. I think if we can carry our bbs to 35 weeks n beyond, we will be quite 'safe' liao.
Chris, I read from from those pregnancy books also. 1 bb born naturally, the other, due to change positions, born by c-section. I dun wan to 'suffer' two times. So, i'm opting for c-section already. My gynae has asked me to pay for the deposit for delivery fee. But, i have discussed wif hb, if I might deliver before 35 weeks, i will go to kkh or sgh too.
