55 days left and DS2 doesn't have a name yet. Middle name will be Samuel. Last name is 3 syllables and starts with a P. Also, has to go with big brother Ian.
Elliot is our top pick right now, but I love Henry (not an option for us), so I voted Henry for you I would toss Milo from your list- something weird about the flow of Milo Samuel.
Not a fan of Elliot normally, but it fits the sibset and middle name well, better than the others IMO. Elliot got my vote. Dominic would my personal preference of your list (if I were just choosing it as a standalone), but I think it doesn't fit all the other criteria as well as Elliot.
