Not read the whole thread but I am completely in accord with the need to work. Shame it gets polarised on here but I think the OP is saying she wants to work and it's an important part of her identity but that this post/this arrangement is not working.
RoseIrene - I work ft and I love it but I couldn't cope with your commute. And it sounds like your job is very demanding - billable hours and all that. I work in the investment advisory world and I used to be on the client side. Post baby I now work on internal stuff so no need for travel or billable hours. I'm sure in law the billable hours are an important part of your career ladder but perhaps you should not worry about the career ladder for now. I am still in my job that I love but I know the next five years will not be about enhancing my career but just keeping a job!
Also, I don't want to get flamed for this but if you are still expressing, it's no wonder you have no time for yourself. I am bf morning and night and that is quite enough and I'm giving up this month (8mo). It is really really draining and I would hate to have to do it at work. I'm amazed that you are still managing to express (I hated it with a passion - number one worst thing about being a mother imho).
It sounds like you are trying to be supermum and you need to prioritise. That doesn't mean giving it all up to sit in the garden. But look at giving up on the expressing? A different job without the billable hours pressure? Differently located job without the commute?
I know it's annoying but I found my company were delighted to get me doing internal things because nobody else wants to do them! They are all so busy wanting to make money that they don't want to "waste time" on corporate housekeeping like HR, training, finance, compliance etc. My job is now that I take our advice and turn it into written pieces for use across the firm as learning and training tools. It's actually really interesting. I was resistant to doing it as it seemed such a "mummy track" (ie, stop earning money for the firm and start looking after people via HR and training) but it's actually allowing me to stay in a firm I love and stay engaged without ruining my life.
I just read saladsucks' post and it seems I have copied every word she said
