Hello, I’m a first-time mom and I’m just wondering when you should/can switch your child from rear facing to forward facing. My husbands sisters boyfriend, who has a 6 year old told me I could switch him based on his height. My sister in law says no way! So I’m looking for more opinions 😂. I just want my sweet boy safe :) he is 14 months. At his last appointment (July 31) he was 22.8lbs and 2’8”. Thanks for your help!
