I'd also like to add that I really hope that Mrs. SD is successful in this coaching up endeavor, because I'd hate to (but would have to) start a thread about excuses for why the SD's can't teach the little SD's not to kick the back of the car seat. I'd be embarrassed (but would do it anyway) if it was a thread that had to be edited like "Excuses as to why mom and dad SD can't teach the little SD's to not kick the back of the car seat 2016, 2017, 2018"
