Egg in a sock??

Be

So an older lady I was talking to the other day told me of this old wives tale. If your baby is teething, it is said that placing an uncooked egg in an unwashed sock of the babies, and hung in the room where the baby sleeps, will take away any discomfort and pain associated with the teething process. She swore by it and said it helped all her kids and grandkids. I thought she was crazy but I listened to her anyway. Just now I googled this “remedy” and apparently I guess it is a thing. Who knew?? Anyone heard of this?? 🤔
