Booking reward flight for unborn baby

Hi guys, it's been a while since I've flown with VS/posted on v-flyer. Hope everyone is keeping well.
So I've got a bun in the oven, hopefully ready to come out in a few weeks' time
I tried putting some reward tickets on hold this morning for next year, and wanted to check a few things with you knowledgeable bunch (as I think the agent was wrong):
1) Can I add an infant with no birthday or confirmed name yet to a booking, or does it need to be done only after she is here? Agent said it needs to be the latter.
2) Does there need to be a reward seat available if I were to use miles? Agent said yes though website disagrees (but I can't use the website as the infant doesn't have a name confirmed yet). I'm not overly keen on booking the tickets for adults now and then pay the cash fare (quoted at almost £300 - I'd much rather pay the 2k plus taxes, though agent quoted 4.5k).
Thank you in advance! In the meantime, I shall also familiarised myself with a thread from a while ago created by NYLON re tips on flying with infants
