In which L's parents go to hell, again
This object was handed to our son on one of his physical therapy visits, as a way to help L relieve his teething pains. Its distinguishing characteristics are:
1) It's made of soft silicone.
2) If you squeeze one of the top three points of the star, it vibrates.
3) It has the blue handle pictured for easy grasping.
4) Yes, both of us independently had the same thought you just did, even upon first laying eyes on the thing.
It's a relief he only merely tolerates it. It would've been very disconcerting had he taken an immediate shine to it. Our house is weird enough, and now we have My First Marital Aids lying around...
