I used some fabri-tac glue around the wrist posts and though it did the trick. The hands still swivel but if you pull her elbow will come apart before her hand comes off. My four year old is relatively good with her dolls though they all seem to like to end up naked. With this one she is so afraid to lose her hand again she has decided to leave her dressed. I do think most six year olds would destroy a doll like this in no time. If they just beef up the joints a bit they would fair much better.
I am still on the fence about keeping Frankie Stein or returning her so for now she sits in her box to be admired.
