The reason for this question is based on things I hear the older women in my family say. My mother says chewing keys isn't a big deal, that it's good for immune system. Aunt and grandmother say there are too many germs on keys. Me personally it quiets my 1-year old son quick in those moments I can't take time to calm him down, keys do the trick - my son is mesmerized by them, lol. I have tried the toy key sets, but my son likes the real thing; he always tosses the toy keys.

Anyway, what have you ladies been told by the ladies in your family? Or your own thoughts? Just curious about the family advice that older women like to pass down to us new moms.
