Yeah, I guess you're right. I didn't notice it at first, but now that it's been pointed out, it'll bug me. I prefer Silas Theodore over Theodore Silas.
We have two girls and a boy right? I like Leah Emmeline, but I don't know about using Isadora Penelope with it. What about using Rosalie Aurora or Isobel Rosalie or Anya Rosalie or Isobel Anya or Anya Isobel or Emilia Penelope?
