It was suggested that materials be stored in a manner they would be used. As I put away things that Ethan used, I will keep in mind when Emily and other future children may use them and how I can store things so they can be easily switched out. Also as Emily grows out of things, I can have them ready when Cruz will use them.
Since I will have mainly infants and toddlers, they will sleep at different times. I will plan things they can do that will be quiet when others are sleeping.
