E.M.
no one seemed to agree with my choice to leave my son rear facing (he is 2 now) and i tried to ignore it as i was the only one that usually took him out anywhere. but when we flew out of state to visit family and they said they had a car seat for my son i was very uneasy to discover that it was not a rear facing seat nor was it installed properly and they were getting upset at me for reinstalling it at the airport. i ignored them at the time and when we got back to their home i got on the Internet and looked up some of the pro-rear facing videos on your tube. i showed them what could happen to a young child if not rear facing or if the seat was not installed properly and asked if it was worth it to risk the child's life. no one said much in response but they left me alone about my choice. send your in laws some videos like that maybe it will click a switch in their head. Good luck and # 1 importance is the child's safety i love my mom but she doesn't think about the safety of my son so i try to not leave him alone with her. price we have to pay to keep our kids safe
