Done the story, can't sleep in the bed

Ok, so I got through the story, now John is at the Beecher's Rest farmstead with the family. But I can't go to sleep in the bed now. I can go up to the bed once and it'll ask me if I want to sleep and if I press the button he just sits on the bed. Then if I get up to try again it only gives me the option to fast travel but I can't get the prompt to sleep again.
