Hi parents! At what age is it 'risky' to get pregnant/deliver? And what are the risks?

I agree with 35 being more on the riskier side, where the gynae is also more particular about the down syndrome test. However it also differs among individuals taking into consideration your health condition, lifestyle or family history. Various reasons can put you into the "high-risk" group not only age. The risks can include preterm labour, preeclampsia or slow growth of foetus. http://www.m.webmd.com/baby/guide/high-risk-pregnancy-overview
