L.C.
I understand your issue. I was lucky that at the time I had my first child, they were doing a trial work at home program. I was able to go p/t for 6 months after my daughter was born, and then after that I worked at home 3 days and in the office 2.
I am sadly no longer at that job and am having a hard time finding a company that will let me work at home or go p/t.
Maybe you could ask for a 6 month trail basis to see how the new schedule goes.
Good luck.
