When I was little, I didn't have the traditional imaginary friend. I had a pet "worm" named Charlie. I would freak if someone went to sit down on "charlie"; and he was everywhere - on the windowsill, at the dinner table - you get the picture.
Julien has "monsters". The number of monsters changes by day, and they don't have names - they are colours. He has a yellow monster, a green monster (these are the 2 that are around the most) and then he has also mentioned a blue and red one occasionally as well. Often when he is getting a snack, he will take 2 - 1 for him, and 1 for his monsters to share. He will hunt around the house until he finds them.
Do your kids have imaginary friends? Who or what are they?
