DS, age 4, has had his lovey since he was 5 months old. It's one of those little blanket animals (teddy bear head with a blankey attached), and I love it because it is small and easily portable. We have 2, and he knows there are two. He leaves one at preschool all week for naptimes, and has one at home. They are frequently washed because I wash the home one when he is at school, and the school washes all bedding once a week, and it just goes in with that.
