I'm glad I bought these! My toddler daughter is in a phase where she wants to swing doors shut behind her before anyone else can get in. Because her hands are so small, she's always trying to wrap her fingers around the door to get a better grip. These save us the tears from getting her fingers caught. They're very lightweight, so I think I'm going to put them on little pegs by each door so that they can be put up or used whenever we need them. The material is like a very light foam, so don't let your kids chew on them.
