At least the flavor of garlic goes through breastmilk!During a recent serial bout of headcolds/stomach flu, my two sons and I cycled seemingly endlessly around each other. I read online (here?) about eating a whole clove of garlic to stave off illness, so I tried it. (Note: chew and swallow quickly!) My now-verbal 2 1/2 year old reported that my milk DID taste different, and he really liked the taste. I'm hoping/assuming that some of the antimicrobial properties of the garlic passed through, too!
Good luck with the eye stuff!
