There is a picture book that I really like about sibling rivalry/camaraderie. At one point the two brothers in the book bond over a long line of things that they build with all the toys that they both own. It’s very sweet and I like reading this particular part to my children, however, I am happy that they never tried to reenact this.
They definitely own enough things for a line going all the way through the house. Even though we are trying to keep the number of toys down, more and more little things keep on coming into the household. It’s unavoidable.
