Yep, Katie, that was the point. "We" spend time online fussing about the .5" of chest clip placement that is very unlikely to matter in an accident instead of worrying about the unrestrained toddler three houses down. So long as it's on the sternum & not belly (vaguely aligned with armpits) it will do its job. There are sooooo many bigger fish to fry. (At least three presentations I attended discussed major vs minor misuse and it was such an eye-opening reminder of where we need to focus our advocacy efforts.)
Diono's Alanna Pinkerton & CSO (carseatblog)'s own Kecia gave a FABULOUS talk on Social Media and CPS that IMO should be required for anyone who wants to tech or advocate on the Internet. To give credit, my second sentence above is paraphrased from that presentation - but it reflects my feelings on the matter as well.
Sorry to derail, Allie! I don't mean to dismiss your concerns about the wellbeing of your child! Rest assured he is very well protected with the chest clip in either position, so long as the install is solid, her straps are at/above and snug on her body.
