I thought you should know about this site called Plush Memories, they specialize in finding lost toys. We experienced this with Olive at age 3 when she lost her pink rabbit. Pink rabbit has been with us since 3 months of age and I'm happy to say is sleeping soundly with her tonight...thanks to this site. You can post what you are looking for and folks will help you find your lost lovey. The search is entirely free and you may want to take a look to see if one of your unwanted toys can become someone's lost lovey.(Pink rabbit is the one on the right)
So word to the wise...if you child is in love with a special blanket, or plush toy, buy an extra one just in case.
