I was really interested to watch about milk sharing since I have shared milk, my niece has received milk and I have a sister-in-law pregnant with triplets who is considering a wet nurse. Channel 4 also links to a "Breastfeeding Help and Information" Page filled with resources, links and organizations in the UK that can help moms successfully breastfeed.
I'm not sure how big Channel 4 is in the UK (their programs do include popular US series such as How I Met Your Mother, Desperate Housewives, Ugly Betty, The Closer, Smallville, etc.) but I am intrigued that they included a program specifically about breastfeeding/breastmilk plus they have a link on their homepage about breastfeeding resources.
Locally, we do have QTV airing breastfeeding commercials (only during August) but apart from being featured in talk shows or the news (if there are newsworthy events), I haven't come across a local channel airing a documentary entirely about breastfeeding. One episode on I-Witness entitled "Kape Para Kay Lean" focused on malnutrition in the children of Pasacao, Camarines Sur where children never taste milk from their mothers but are fed with rice coffee instead. Looking at the local major stations's TV show line-up, I think that a breastfeeding documentary could be a proper topic forThe Correspondents or Dokumentado or I-Witness.
