He's also probably been stuck in that hole since he was born. Lori, Leni, Luna, and Luan all once had their own private bedrooms, but the birth of Lynn probably resulted in Leni and Lori bunking together. and when Lincoln was born, rather than stick him in the same room as two toddlers, they swaddled him in the 2nd floor sitting room, which became his bedroom.
After that, with each subsequent girl the family began bunking them together. Lincoln hasn't got a snowball's chance in hell of ever getting his own full sized bedroom, since, even if Leni and Lori leave for college, the other girls will start migrating to gain individual bedrooms long before Lincoln has a chance.
