Car seat vs husband

MA

Let me start by saying my husband is an amazing dad in every aspect but this....

With that being said I have to vent.

Our 1 1/2 year old son is in my car about 95% of the time but I have noticed that when my husband straps him in he does it wrong most of the time (the chest clip is down by his belly, the straps are twisted, he is slouch over or crooked in the seat) I will tell him he has done it wrong and tell him how it needs done and he gets defensive about it. I have shown him the correct way multiple times and have told him that it is dangerous for our son if he is in there wrong but he still does it incorrectly. It drives me crazy and makes me worried for the times I’m not around to correct it!

I would never be able to forgive him if there was ever a wreck and something happened as a result of him being strapped in poorly.

Does anyone else deal with this or does anyone have any suggestions?!?
