Newborn with low TSH levels (Thyroid function test )

Dear mummies , My newborn blood was tested with low TSH levels less than 0.01, I’m worried it may affect her brain development according to the PD. It is said by the PD that thyroid antibodies are passed through by the mothers during pregnancy . My newborn is scheduled with an appointment with a specialist in KKH this week. Any mummies have similar situation with their newborns with low TSH levels or thyroid issues ? #advice #firsttimemom
