Baby Mouth to Mouth

No we are not talking baby CPR here...we're talking about the latest controversy of Alicia Silverstone feeding her 11 month-old son food that she pre-chewed and then "spit" into his mouth.  We are all moms here (at least I'd be surprised if we weren't) and I'm curious what your opinion is.  Is it natural?  Gross?  Safe?  Sanitary?  Do you do it or is Alicia alone on this one?  Take a second and leave a comment!
