Support for Parents of Girls 9–16
Big Sister Letters helps parents and caregivers support girls ages 9–16 with monthly letters, thoughtful guidance, and age-aware encouragement delivered by mail.
You don't need a script. You just need a starting line.
Her letters are written for her, but you are never left guessing. Each month, before her letter arrives, you receive a private companion email so you know what encouragement she is receiving and how to support her well.
The monthly preview email
Before her physical envelope arrives in the mail, you receive a private email with the month's theme, a preview of her letter, and simple context on why this topic matters right now.
Meaningful chats made simple
We know how hard it can be to get more than a one-word answer. That is why every guardian email includes a gentle, age-appropriate game plan to help you support her naturally.
The example she lives beside
Sometimes the most powerful guidance is not a perfect conversation — it is the example you live beside her every day. We help you notice the messages she may be absorbing and offer simple ways to model steadiness, respect, and self-trust in everyday moments.
How to get started
Choose the Pre-Teen or Teen subscription that fits her best. Enter your email for the guardian companion emails and her mailing address for the physical letters. We handle the rest.
