I've had this happen. I think I figured out what causes it. I've seen my toddler holding/using something like a tablet but then he sometimes "puts it away" (into his pocket presumably but not his inventory) when he wants to do something else such as talk to someone in another room. Then after that, he doesn't take out the item again so it's kind of stuck in limbo. So if he then tries to go to sleep, that causes him to keep getting into and out of bed. I can work around this by:
-getting him to do other actions until he takes out the item again
-clicking on the troublesome item in his hand (perhaps while the game is paused, to make sure I can do it), and choosing an action involving it such as Watch Toddler Videos
-then, after unpausing the game and seeing him start to perform that action, immediately cancelling it, which should cause the toddler to put the item down or away properly.
I hope that made sense. Ask me if you have any questions.
