I am having trouble dealing with people who do not understand and sometimes quite shocked at my decision to not go back to work full time once the baby comes along. It mostly comes from women who have not had children. I am getting to the point where I do not wish to discuss the question of when am I going back to work.

Basically my situation is:
My position needs to be full time and I only would want to return part-time and I cannot work some days from home.
Childcare is scarce in my area, so even if I wanted to go back full time, I cannot guarantee when I can, if I can. (I dont drive and we have only 1 car which DH needs to go to work at 5:30am, so I am limited to childcare within walking distance) Also the cost of childcare is scary.
I need to start bringing in some income after 6 weeks. So I can't take the 12 months to think about what I want to do, or to see if work gets busy enough to put on a part time position just for me.
Most of all I did not decide to have a baby only to put it in fulltime child care straight away.

Anyway my solution has been to start bookkeeping from home, that way I can bring in some money and not have to put the baby in childcare. Also for a lot less work and hopefully hassle I can bring home the same amount of money as if I was working full time and paying for childcare.

So my questions are
is what I have decided to do unreasonable? and
how do I deal with those who don't understand and so I don't have the full explantion each time?

Thanks Astrid
