Does your toddler have a security blanket/ stuffed animal + should you take it away from your toddler?

My daughter has a blanket and stuffed animal that she sleeps with every night. She doens't carry them around with her or anything, but she hates to sleep without them. And no, I haven't taken them away. They haven't gotten too dirty, as she doesn't drag it around wherever it goes. It stays in her bedroom and that's it. She's only three, so it's not that worn yet. ;)
