Oh Minks you sound so distraught. Am sure Kit will be fine but I totally sympathise especially with your relliance on public transport too.
I can't add anymore other than to agree with you about being a full time Mum. Our main issue is the cost of childcare for two, we have no family nearby to help with childcare so all my wages would go on on looking after the twins. We could see no reason for me to go back to a job I hated just to pay the childminder! I am now doing some book keeping for hubbie's business during lunchtimes and on the one day they go to the childminder, and finishing my diploma so I can set up my own business.
My other issue was finding childcare that was suitable, my childminder can only offer me one day because they are twins, nightmare. The closest nursery to us is £5.50 an hour each, with no discount for the two of them, plus food costs on top, another £2 a day!
I hated leaving them the first day, and cos I'm working at home the house was so empty. I have got more used to it now and get lots done. I also try to go for a run with a friend so I get some me time. So maybe try to go running while at work to make use of your time away from him. I know lots of Mums who do this!!
I do hope it gets better for you.
