Is there a difference between an obsession and an addiction?

Perhaps, she is simply revelling in a short-lived pleasure. "In the Night Garden" is a pleasure, whether it is short-lived remains to be seen.

Her absolute favourite character is IgglePiggle, She can sing along when Derek Jacobi sings the IgglePiggle song: Yes, my name is Igglepiggle Iggle piggle wiggle wiggle piggle Yes my name is Igglepiggle Iggle piggle wiggle wiggle woo! Igglepiggle doesn't live in the Night Garden. He travels there by boat each evening, on his way to sleep. With great gusto, she can name all the characters: Upsy-Daisy, Makka Pakka, the Tombliboos, the Pinky-Ponk and the Ninky-Nonk, The Tittifers, and the Pontypines. Even the Haa-Hoos.

Can an 18 month old child have an addiction? Perhaps not. I shall think of it as a short-lived obsession that brings her immense pleasure. I have allowed her to watch two episodes on my computer, but her Mummy would prefer that she stick with the books and the CD and allow her imagination to do all the rest.
