soothers are the most often used item..yes i hate them! but they have a purpose...I just dont like to see children over the age of 2 with them!
blankies are the second favourite, I think. Most kids have a special blanky they have.
some children have a special toy, like a bunny or other stuffed toy.
My niece used to LOVE her tag on her whale...rubbing it on her nose

My youngest actually never had a special object..at least not one that she could take with her..boobies belong to me lmao!
