My in-laws were very keen to get ds in a forward facing carseat. They had installed one the first time they visited when he was a week old (just incase we went somewhere).
Anyway, I have kept him rear facing until a year and he was the right weight. They have been taking him on little outings over the last couple of months. I didn't mind occasional use of the forward facing as he was the right weight and they said it was a high quality one from my sil.
Was going out for the day with ds and Mil kindly picked us up. Went to put ds in the seat and asked mil how to adjust straps as they looked too big. She then had a quick pull on them and said all done. I checked again and realised they are still on the settings for sil's son (would have just turned 4 when last in use). Not only that, but the strap between his legs was not attached to the seat, only the fabric. I started trying to fix all this (ignoring cats bum face). I couldn't adjust the head rest. Mil said it was on lowest setting. My ds is really tall, so I questioned the grouping of the carseat. Mil had no idea.
Well, if you managed to read all that...I'm fuming! Mil was not concerned by any of this and was more concerned about getting going. I feel sick that my ds has been driven all over the place (motorways) in a seat he could have wriggled out of.
Aibu to wonder how someone so intelligent could have such a disregard for safety?
