I can't believe it's almost go time! Excited for all of us

Would love some help choosing a middle name for my little guy. Henry is definitely the first name. I'd like his middle name to start with S. Right now Samuel and Simon are the front runners. I'd love votes and other suggestions, as I'm sure there are S names that I haven't thought of!
Thanks ladies!! Good luck to everyone.
