It is for children of all ages. 

When we think about it,  we have all been six months old and four years old and seventeen years old and – well, you get the idea.  It gives a different perspective to life when we realize we don't leave these ages behind : they are part of our tapestry.  And we understand what it is like to unroll magic string from our hands and toss it up to a seagull and use it as a kite.
