I'm looking at what conferences are out there, thinking about a blog I'm definitely looking at an arts subject, but with a neurology/psychological/religious studies angle, suppose it means there'll be more departments to approach??
Evidencing what I've done while at home would help wouldn't it, the various subjects that I've read up on and how the experience of motherhood/sahm has impacted on me and my critical thinking etc.
I did Ancient History for my degree and they were surprisingly amenable to me switching to modern medical history but I had to show my thought process as to how I got from one to the other.
In my case I mentioned I had worked in a care home, was interested in urban exploration websites and in particular old asylums, which had guided my reading for a few years etc. I had also done a social care course with the OU and another in Psychology which helped too with evidence of commitment, independent study and interest.
I have read a hell of a lot since I have been a SAHM, I read a many of the 'classic novels' as I could, hundreds of history books and really developed my interests. In the informal interview with my supervisor a lot of it was just chatting through interests, potential proposals etc, trying to align research interests. If I hadn't done any reading it would have been much more awkward.
With the SAHM bit I said (with a smile on my face) that it had improved my patience, negotiating skills and confidence. That it had made me much more organised and responsible and able to juggle tasks and prioritise ( and I referenced studying with DCs when I was doing my OU courses too).
Blog sounds like an excellent idea. I wish I had thought of something like that. You could really develop it over a few years and it would give great evidence of your commitment and enthusiasm to the subject.
