Yes, we both live at home with the two kids, and grandma will be watching the kids. I work full-time, my wife will work 3-days per week, grandma will be home with the baby and help with after school transitions for the 10 year old. Once she leaves, the baby goes to daycare 3 days per week and the after school transitions are a bonafide burden to our employment.
I won't say that we are not enjoying grandma's company and cooking, but this is fully legitimate child care function.
I suspect my issue may lie only in work-permitting, but I'm looking for validation here.
