It seems to be stuck sleeping or is there something I have to manually do to make it stop? If so I can't figure it out. It's not the biggest deal if the game is frozen and I have to restart since it's at its first stage but kind of annoying.

The digimon sleeps for at least 8 hours once it's put to bed, It can sleep more hours if the sleep counter still hasn't reached 100%. Every time you put it to sleep, a window will tell you the time it will wake up.
