I'm very happy for you and I do understand how bittersweet it is. I have experienced the same and through the happiness and the joy felt, so is sadness. I can imagine what you're going through with her delivery date being so close to your precious Sean's dates and for that, you truly have my heart.
I love the name, Seanna. Is it pronounced "S[h]e-anna"... or "Sean-na?" I was just curious!
Sean will live on in her life as you will tell her stories and include her in all of his special dates. It's the only way we keep them alive. It's all, any of us have left to do for them.
Thanks for sharing your news with us and please update when this beautiful child arrives!
Hugs & Love!!
