I think it's very sad that being a SAHM is viewed by so many as demeaning. It's the most important job in the world. I know I'm now going to get the p!ss taken out of me for making that statement, but the hand that rocks the cradle...
And it's the most difficult. There's no working time directive, no negotiation, no defined lunch breaks, no holiday pay...
No, I'm not a SAHM, nor do I wish to be. I've found what I consider to be a very happy compromise (I work 3 days, DD1&2 each have 1 day with grandparent, 2 days at nursery,). This balances my need for my job, which I enjoy, and my need for my children's primary caregiver to be one of their parents.
I was probably of the career first mindset until I had children. I worked 4 days to start with, and hated it, hated what I was missing out on. But, oddly, 3 days and I'm happy. Now I think that SAHM is more 'normal' than 'working' mum
