The sex of the baby will almost certainly be recorded as female. Keep in mind that while the karyotype might indicate XY, babies generally aren’t karytotyped at birth, as that’s a pointless expense for the overwhelming majority of people. The parents, doctors, and children wouldn’t have any idea about their condition until:
Streak gonads are detected, which involves an MRI or ultrasound
Hormone levels are measured in a blood test
The child fails to undergo puberty as expected
Since only #3 is visible without a specific test, it’s usually the first indicator, and the other two tests are used as confirmations of the syndrome. That’s when supplemental hormone therapy and surgery are discussed as well.
