If you've ever had one, you'll understand.

Photographer Niki Boon is living with her four children on a 10-acre property in New Zealand and tries to document their everyday carefree life in natural environment. Her children aren't schooled and she believes that they "are right where they belong covered in mud."As a gift, Niki gives each child a pile of their photos on his or her birthday as these photos are a little treasure which will later tell their childhood stories.
