Do we need to list infants if using buddy passes on United?

[Number30FTO]

My brother is using one of my passes and he's traveling with his 7 month old.
I've asked gate agents & I'm getting mixed answers. Has anyone ever done it
before?
I don't see an option on Intranet to list infants but I may be missing it.
Also, it's an international flight.
TIA

The infant will require its own buddy pass on an international flight.
