35 weeks 1 day safe po bang magdeliver ang gnyan? may nangangak po ba ng 35 weeks ?

I gave birth to my 2nd baby at 34 weeks and 3 days via cs due to hypertension. ok nmn sya pagka labas nya he was small at 4.12lbs lang didn't require special care, hindi rin sya na NICU. Pero eventually naging sakitin sya labas pasok kami ng hosp. due to pneumonia, he is also autistic. 8 years old na sya ngayon high functioning naman, but still autistic. If his autism has something to do with being born early, I don't know, pero mas mabuti ng mag pa full term ka mamsh, kahit 37 weeks na man lang para fully developed lungs nya.
