Hypothyroidism is common in some
pregnant women. Your doctor has done the right thing and started on treatment. From the baby's perspective, there is nothing to be worried about.
Although your baby dies have a higher chance of being hypothyroid, you needn't worry. His brain development will be absolutely fine.
Next Steps
All you should do is ensure that your baby gets his
thyroid level screened by a blood test, which is usually done at 48 to 72 hours of life. Speak to the attending pediatrician at the time of delivery and they will guide you about this simple blood test.
