Do i need to take 3 yr old son with me for H4 biometrics/interview to mumbai consulate?

I am scheduled to attend H4 visa interview/biometrics in Mumbai shortly along with my husband who is also attending the interview for H1 .All our docs are in order. We have the DS160’s also along with interview confirmation letter and also have a photograph done for our son . Just need more clarity on whether it is necessary for very young children to accompany parents for biometrics/visa interview. Any inputs appreciated.

We took our kid who was 6 months old for the interview.
