I saw the very same episode myself, I was not happy about them not showing or
making any mention of breastfeeding either... <sigh> the rest of it was very
interesting to my 3 year old who spent last night in the hospital with us for
eval of Prodromal Labour.  I have seen on other programs where PBS has a
website that you can access (if your computer is not being picky, like mine is
tonight...).  It is at http://www.pbs.org I can't remember off hand if RR has a
page, but it might be a start.  From what I have seen, this is pretty common on
RR, Kratt's Creatures, OTOH is excellent about portraying nursing couples of
all species.  This week they showed some babies nursing from their moms and my
son was very interested in this and talked about it for several hours after.
