I am unsure exactly when the SS# was issued, but it was likely after the deadline. We delayed getting it for a long time as we live abroad, and it required us to travel to the nearest embassy. Didn't want to do that until vaccinated.
Struggling to think of a good reason why they'd turn away people with an otherwise valid claim to that credit, particularly people just starting out with a new baby. But I guess I can only blame myself for not knowing the rules.
Thank you for the detailed response. Much appreciated.
