Good to hear about your friend managing to remain popular, whilst being an earth mother. I'm currently slightly failing in both and wondering which to pursue more avidly.
About placenta burials Moondog .... I had two babies at home in London and delivered the placentas into my favourite mixing bowl. (yum)
DH bought, in the first instance a Corkscrew Hazel, and in the second a Fatsia. Each time he dug a hole and we tipped in the placenta (SPLAT!) then planted the bushes above. Both did very well in soil which, I have to say, was particularly fertile for Brixton.
My next two babies were born in Brighton and we did the same thing, but with two Eucaplyptus trees. Both continue to thrive.
A real hardcore Earth Mother would surely make her placentas into pate and have a placenta party for family and friends (God help them!).
I heard somewhere, and would be interested in corroboration of this, that the hospital sell placentas to cosmetics companies who extract some stuff for their products. Bluerck!
LM have you tried the mooncup? I find it absolutely brilliant and so much less yucky than tampons or, even worse, sanitary towels. Even my sister, who is by no means an earth mother, loves her mooncup. It's the way forwards.
