Hello, I have gone through your query and understood the concern. The fetus attains maturity at 37-38 weeks of gestation. So, a baby delivered at 37 weeks should not have any problem as the lungs are mature enough to provide proper ventilation. If you have a growth retarded baby at term, it is always better to deliver the baby in order to remove the baby from the factors hindering the growth within the uterus. The fetal parameters and the biophysical profile are important in the decision. Most often, the outcome is good. You can also take a second opinion if you are still in doubt. Wish you safe motherhood.
