Very interesting. I'm not surprised about Prince George, Princess Charlotte and Meghan's friends' daughters (Litt & Mulroney) and the Mulroney twin boys. I did not know much about Harry's goddaughters, but I knew his friend and mentor Mark Dyer's son would be in the wedding party.
I'm kind of surprised that there won't be an older young lady to help keep those very young rambunctious children in line. I was thinking that 14-year-old Lady Louise Wessex (Prince Edward's daughter) might be asked to serve as a bridesmaid to help with guiding those younger children.
This is going to be very interesting, especially if all of these youngsters are going to be in the car with Meghan! Probably only a few of them will accompany Meghan in the car to the church. Meghan is excellent with children, I know, but this is her wedding day after all. If the children all have calm personalities, perhaps they will behave. I'm sure they will all be very cute and look sweet in their outfits.

Maybe Jessica Mulroney and/or Mark Dyer's wife will be at Meghan's side with the children prior to the wedding party entering the church, and they could help. I would imagine that the children (or at least the very youngest) will be taken to a separate room in the church during the hour-long ceremony. Children can be understandably restless.
I'm not sure what the latest news is on who will walk Meghan down the aisle. I won't be surprised if her mother does the honors. Personally, if her father isn't healthy enough to be there, I would hope that Meghan's friend, Markus Anderson, could walk her down the aisle. He's been like an older brother to her, and they have been extremely close. That's probably why he was included to sit with Meghan and to be in the box with Meghan and Harry at the Invictus games last September.
