Thank you for the response and the link to the article. That's an interesting angle which I hadn't thought of. From what I know, I believe it is a problem that has spanned generations, stemming from implementation of a residential school system. Someone pointed me to Cindy Blackstock who is a big advocate for Aboriginal rights and sheds some light on the challenges faced here in Canada. Here she talks about the discrimination against aboriginal children in Canada ( https://www.youtube.com/watch?v=ahGQ0WBd0ng&t=362s )
The Mummy Monitor sounds like a fantastic idea and may well be one possible solution. I have a few connections which I am pursuing to hopefully gain some further insight into Aboriginal motherhood in Alberta - an executive involved in the Merck for Mothers Alberta program, an academic at the University of Alberta, a support member at the Terra Centre for teen mothers (they are one of the partners in the Pregnancy Pathways program) and I'm also hoping to speak to with a teen aboriginal mother through the Terra Centre.
