Charge 2 stops recording sleep after briefly waking up

I have a young puppy and when I take her out at 5 AM or so and then go back to bed, my Fitbit Charge 2 does not continue recording my sleep.

@MSZ1944 It's great to see that you've visited the Fitbit Community!

Let me help you with your sleep detection. Your device will start recording sleep after it detects an hour of inactivity. If you have a light sleep or move too much then this may difficult your sleep detection. Additionally you can try wearing your device on your non dominant hand to decrease the amount of movement it is subjected to. Finally you can restart your device. You can also manually log your sleep time. You can read more about sleep detection here.

Let me know how it goes.
