I work from home so I do the research and lay out options and then we discuss. We are almost in 100% agreement when it comes to the kids and their education. Due to dh's varied schedule, I am almost always alone in meetings. For the most part this hasn't been a detriment.
But when things ugly he began accompanying me to meetings. DH is the calm diplomatic parent. I've been in the trenches and have precious little patience after the fifth request to accommodate my child. So it was somewhat humorous for me to see DH be the one to get red in the face and stare incredulously as teachers/administrators refused to test, accommodate and differentiate for our children.
It certainly gave him a better understanding of the obstacles we were/are facing.
