But what we also want to know is, will the Duchess of Sussex channel her late mother-in-law, Princess Diana, in her baby debut outfit?
Royal fans will know that Kate Middleton's baby debut style was highly influenced by Diana.
Both women stood outside the Lindo Wing at St. Mary's hospital in London, alongside their husbands, cradling their newborn children.
Kate's red Jenny Packham dress she wore when Prince Louis was born was almost identical to Di's red outfit from Harry's baby debut.
The Duchess of Cambridge was also highly inspired by Diana when she welcomed her first child, Prince George.
Her polkadot dress, again by British designer Jenny Packham, was very similar to the dress Diana wore when William was born.
But will Meghan do the same and honour Diana by wearing red or blue on her and Prince Harry's big day with their baby?
We already know that there is doubt over whether will even give birth at London's Lindo Wing. It's likely that Meghan will break royal family tradition and give birth closer to home, in Windsor.
Only time will tell, and with Meghan's due date nearing, we don't have much time left to wait!
