Most babies are born healthy. Still, it is wise to have the baby’s weight and position as well as the mother’s blood pressure checked regularly during the pregnancy. Ultrasound scans are also part of the regular check-ups. Apart from these routine checks, there are a number of other tests that are part of the prenatal diagnostics. Some of these tests may be useful, but please be aware that there are very few ways to influence the child’s development before it is born. Parents should consider very carefully which tests could be helpful for them, and what could be done for the unborn child if a defect is diagnosed. Prenatal diagnostics can cause a couple to consider terminating a pregnancy which they had fully supported up to this point.
