Do you have a double-door closet in your upstairs hallway? Turn it into a reading area. Loft areas and open hallways also work well as small library spaces.
Alcoves. Once upon a time, your charming hallway nook may have been your very own reading spot. However, it may be time to hand it over to the kids. Swap out your novels and back issues of Vogue for picture books; giving them a comfortable place to relax will also encourage them to read. You can always sneak back in for a relaxing glass of wine after bedtime.
