To add your partner to the app, head to your Me page and tap "Add your partner" in the upper right corner of the screen. Then, follow the instructions to link your accounts (you can even send a text message alert). As soon as you've submitted your partner's email address, your accounts are linked!
To login as a partner simply download the app and tap "login." Then, enter the same email address that your partner invited and create a password. You'll be all set!
Please note: when you connect with your partner, you are adding them to a baby profile. If you have more than one baby profile, you will need to add your partner to each baby individually. For this reason, if you already have a partner in Glow or Nurture, you will need to add them again.
