Worrying about her future children

LB (age:  not quite 5):  "Mama, I need you to save all of my toys and my bed so that my children will have something to play with and somewhere to sleep when we come see you when I grow up.  I also need you to save IB's stuff too for her children.  And...I need you to save the big beds in the other room so that I will have somewhere to sleep."  Hoarder in the making???
