H4 Biometric for Kid - received letter of reuse for parent

Hi All,

My Spouse (H4 extension) received letter from USCIS that they are going to utilize previous biometric and changed status to " Case Was Updated To Show Fingerprints Were Taken" online. But for my kid (7yrs old) doesn’t receive such letter or no change in status. Let me know for my kid alone I will receive biometric appt in future? or any other way to check if they can use old finger print?

Anybody having similar situation?

Note:
Spouse and Kid - both did fingerprints last year for extension
H1B + H4 filed around May 2020 and H1B approved in Jul through premium

Your kid should receive a biometric appointment letter unless USCIS has mentioned anything else in the letter.
