The two issues pictured above I have seen many, many times and are both potentially deadly. Simply put the Chest Clip and the Locking clips need to be in the right place at the right time as pictured above…

Fortunately the newer cars have these anchors pictured here to save you from dealing with that strange looking locking clip usually attached to the bottom of your seat.

Then there is the whole issue on using seats or boosters as long as you need to… I do love this picture..

Then how easy is it to check to see if there is a recall on your seat or more importantly if it even meets safety standards get it registered here:  https://www.safercar.gov/parents/CarSeats/Car-Seat-Registration.htm?gclid=Cj0KEQjwicfHBRCh6KaMp4-asKgBEiQA8GH2xy50SBDvdgS43cHJfW6gZtkSfp8ij67OozEcFAwqUWcaAr1P8P8HAQ?view=full

Prayerfully consider how to protect your child, they are counting on you, and God.
