Write a handwritten letter during pregnancy to your unborn child. We'll deliver it on their first birthday, or a future milestone — so they'll always have, in your handwriting, the voice of who you were before they arrived.
There is a version of you that will only exist during the pregnancy. The parent-to-be. The person who is already rearranging their whole interior around a child who hasn't been born yet. You imagine them. You talk to them. You dream about them with a specificity that completely disappears once they arrive, because after they're born they become themselves — a specific human with their own face and voice — and the imagined version you carried in your head quietly dissolves. Most parents grieve that dissolving without having words for it.
A letter to your unborn child holds that version of you. You write during pregnancy — any trimester, or several — and you talk to the child you're picturing. You describe what pregnancy feels like. What you're hoping for. What you're afraid of. What you want them to know about the parent they're being built by, in the months before they could see anything. You seal the letter, we hold it safely, and on a date you choose — their first birthday, their fifth, their wedding day, an adult milestone — it arrives in the mail.
Years later, your child will read that letter. They'll read it in your actual handwriting, with your fingerprints on the paper. They'll meet the version of you that was pregnant with them, imagining them into being, talking to them through the wall of your own body. That's not a story a parent can tell later. It's a voice that only exists while the pregnancy is happening. Writing it down, sealing it, and letting it travel through time is the only way to give that voice to your kid. They'll have it for the rest of their life.
