Carl hope your missus gets better soon,and yes driving for a living is easier than raising kids but definitely not as rewarding.
Been the stay at home dad since little girl was 6 weeks old(she ie now 3yrs)back to work full time for the last year,as she has got a nursery place,but still miss not being at home with her.Unfortunately work is a necessary evil for us single parents.
Take care and congrats on what you are doing and experiencing with the kids.
