Is it weird?
The names are Theodore and Theodora - I love them both but I feel like I'm cheating myself by having essentially the same name for a boy and a girl 🙈. We've been set on Theodore for years.
Boy would be shortened to Theo, Teddy or TJ (the second name will be J, family tradition!) and girl would be Thea (which I love on its own, or even Teddy - depends if she liked it as she grew older).
I also love Seraphina for a girl but DH thinks it's a bit 'out there' - I disagree, but then I'm called Tamara and I'm from a family of non-mainstream names!
I say all this and I'll probably change my mind as the time gets nearer anyway.
