Hi Meredith! We can add your daughter's email to your account. However, we don't have a way to guarantee that all emails will be sent to both email addresses. One would still need to be the primary email on the account. However, you can both access your letters and most of your account information through the app or website. If you would like, I can add your daughter's name to your account so that she will be addressed in your child's letters as well. If you would like us to do this, could you send me your sponsor number or child ID number? I would be happy to update your account!
