The children of the Duke and Duchess of Cambridge are likely to play a part in the engaged couple's upcoming nuptials, which are expected to be very "modern".
Grant Harrold, etiquette expert and former butler to Prince Charles and Camilla, said: "Princess Charlotte is a prospect in the bridal party and Prince George. The baby will only be a few weeks old at the point. I think Meghan will opt for a traditional bridal party, but she'll want to do it in a modern way with their own influences."
The wedding will take place in St George's Chapel in Windsor Castle in May and the couple are thought to be very involved with the planning for the big day.
Harrold added to Express.co.uk: "With a big royal wedding of course there is a lot of tradition and protocol. But when it's a private and smaller affair, especially with the reception, Harry and Meghan can plan more what they want.
"They are two very young royals, they'll have their own music and entertainment they enjoy. They will very much be involved in the planning."
Kensington Palace announced in a statement that Prince Harry and Meghan were to wed at St George's Chapel.
A statement read: "The marriage of His Royal Highness Prince Harry of Wales and Ms. Meghan Markle will take place at St. George's Chapel, Windsor Castle in May 2018. Her Majesty The Queen has granted permission for the wedding to take place at the Chapel. The Royal Family will pay for the wedding. Further details about the wedding will be announced in due course."
