We have 6 boys that all have activities they need to get to. Sporting events, scouts, work...etc. I don't know how she keeps up with it. I just tell her to tell me where to be and when each evening to get someone.
Just because they are stay at home moms doesn't mean they have flexible schedules to meet anytime.
Either way, someone is going to get annoyed. Assigning her a visiting teaching companion that works or people to visit who work complicates things as well.
It just isn't an easy issue.
