In my sons case, there is no way to keep him rear facing. He is 15 months old, and at 13, he legs were so long, his knees were buckling up, and causing him discomfort all the time. I tried adjusting, I even went to the Fire station on the block to have them give me tips. They re-adjusted again. This time, my son kicked and pushed SO hard during the car trip, he tipped the seat to the side and hit his head on the sliding door. So for me, my child can not be rear, I guess I get a ticket it if happens. I do feel confident he will be at least moderately safe in case of an accident.
I do not think I qualify as a neglectful parent, but one that has done what I can to make my child safe.
One: I know the law. I know its safer, I know its suppose to be handled. I even had a professional re-adjust it. My son does not fit the criteria... he is 98% height for his age. He is taller than a two year old. I called and asked if there was a permit or any thing I can carry in-case of a stop, nope. I asked if there are custom car seats for this. Actually no one makes car seats for overly tall. He is in one of those seats made for 5 year olds. He isnt fat just really really tall.
Maybe people here, have not seen what tall kids go through being rear facing???? so a fender bender is equal to two broken knees, ankles, and legs because I have to follow a law fit for normal sized kids? Anyway, if her 7 month old is of normal size, tell this friend dont let it go. She should be rear facing. My girls were both rear facing till 17 months and that was years ago.
