Career & children? Can you have it all?

Hi IM, I am really after some advice & even some people who may be willing to share their experiences. This will be a long post so please bare with me.

My hubby and I are in the same job. Started the same time & have now been promoted. We have 2 beautiful little girls (2 yrs & 7mo) & are pregnant with bubs #3.

The issue (well I suppose it's not really an issue) is I got my promotion when I was pregnant with #1. It was initially agreed I would have 6 months off work, then return back to my duties.

After having #1 we found out that both her and I have a rare genetic condition which can be fatal (we have had 3 previous losses before).

Due to the shock of all this, I decided to take a further 6 months off work. I truely believed that she was a miracle and we wouldn't be blessed with anymore.

Fast forward a few months & we are blessed with another surprise! I return to work pregnant (fair to say they weren't happy) and I work for 8ish months before going off again.

4 months into my leave & we get another surprise. Our lucky last! And one that has shocked our medical professionals as it was a 0.01% chance of survival.

Regardless, I am now thrilled (although petrified) to have our previous 3rd. Due to how far along I am I will be returning to work for 2 weeks max before going off again.

Hubby and I live over 6hrs away from family & due to doing shift work and having another on the way, we realise the best option for us as a family would be to move closer to home. We would have the support of our families (especially with hubby working all the time I won't be so alone etc) and then with me returning back to work, it will help to have the support of family when we need it. It will also help with the massive financial strain we are under.

Anyway, the issue is.. if we leave.. I give up my promotion. I take a step back & then in 5-6 years will try out again and hopefully get the job back again (same job but closer to home). I could attempt to transfer, but seeing as I have mostly been on Maternity Leave etc whilst in the job its highly unlikely I will get one elsewhere.

OR do we stick around until I've been back at work for 12-18isj months (so looking at 2019) and then attempt to transfer them? I will more than likely get a spot then due to me actually being at work (and not being pregnant).

I don't know what to do. Hubby will do either, but I feel it's important for us to be close to family and to get back on our feet financially. OR is it important for me to keep the higher paying job.. but have no family around and hardly see each other?

I feel like it's a no brainer, that I should just pack up and leave. But part of me wants to hold on to that role? Am I crazy? Selfish? I just feel torn. Any advice would really be appreciated!
