Apple Watch not logging sleep

Emily • Our rainbow 🌈 baby has arrived! April 3, 2017.

I just got an Apple Watch and want to use the Glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.baby">Baby app</a> on it to track sleep. However, it’s not working correctly. I have the most up to date app and iOS, so I know that’s not the issue.

When I start a sleep timer on the watch, it will have stopped by the time I check it later in the night. It’s also not syncing with my phone so none of the sleep is showing up on the app.
