Did I imagine this?  I thought I saw a post in the last few days regarding research on mouse pups imprinting on (bonding to) artificial nipples in a pre-birth surgery.  But for the life of me don't know how to retrieve it  -- I thought I had copied it, and it exists nowhere in my files, e-mail or paper.

What subject should I do a search under, nipple confusion?  Will the person who submitted the post mind re-mailing it to me?

TIA, Chanita, San Francisco
