How should I translate "doudou"?

As opposed to what is commonly said, "doudous" don't have a "dream catcher" function. They are not acting like a charm to protect children from nightmares...

They simply help children to resume sleeping in the middle of the night and then, carry on with their own beautiful and cosy dreams.

Most "doudous" are stress free cloth creature!!!

Their dreams are made of images from the day before.

Generally speaking, "Doudou" have very short term memory.

For instance, they do not recall the time when they were sitting on a Doudou shop shelves...

... all tne more so, they do not recall that once, they have been the object of a commercial transaction...
