What is a family?
Who is a family?
One and another makes two is a family!
Baby and father and mother: a family!
Parents and sister and brother: a family!
All kinds of people can make up a family,
All kinds of mixtures can make up a family.
What is a family?
Who is a family?
The children that lived in a shoe is a family!
A pair like Kanga and Roo is a family!
A calf and a cow that go moo is a family!
All kinds of creatures can make up a family,
All kinds of numbers can make up a family.
What is a family?
Who is a family?
Either a lot or a few is a family;
But whether there's ten or there's two in your family,
All of your family plus you is a family!
