What does a plush toys bring to child?

A mother says that her baby has a very favorite plush bear, holding it while eating, sleeping and even out on the street. The bear is pretty dirty now, but the baby still refuses to let it go. She has no choice but to buy a new plush bear which is the same as the old one to replace the dirty one. But the mother cannot understand why the baby only loves the bear, even though there are so many funny toys. 

In fact, the bear plush toy is not just a toy but also a partner or a brother in a baby’s world.
So we recommend a plush toy as the sweetest toy for babies.
