I love both things that I do, but not both at once!
I'm a SAHM to my toddler DD five mornings and one afternoon per week, and it's lovely. And I'm an academic researching medieval sexuality and gender (and trying, and succeeding, to look as if I do it full time). I finished writing my book last month, and in the autumn I'm starting a new project with a research grant that means I'll be able to afford childcare for DD.
I love being a SAHM, against all expectations, because toddlers are actually fascinating and I so enjoy all of her tiny discoveries and victories. I love seeing her learning so much and I feel lucky to be there for that.
I love being an academic because I enjoy teaching (for exactly the same reasons as being a SAHM, plus you get to make young people feel confident), and because I really, really, really love researching and getting to spend days patiently figuring out what happened in the past and why it matters. Right now I am researching how people thought about miscarriage in the past. It sounds depressing and it could be, but it's also making me think how we can gain some strength from the past, and what we can learn about how to support women in the future. I find that really exciting and valuable, so I hugely enjoy this bit of my job.
OTOH, the hours are crap, I'm constantly juggling, I'm working 12-14 hours in the week and 8-10 each weekend day, and I am shattered.
