I FF but DD is 16 months. Not everyone agrees but they didn't birth my kid lol. I feel like people shouldn't get so butt hurt over others choices. However, everything you mentioned is against the law. I FF DD when she was 1 and that was my choice. If the law changed then I'd rear face again but I wouldn't plan on FF before 1.
ETA: I mean butt hurt towards things like FF if they're over 1, not if their doing something illegal. The straps annoy me though too. One time on the highway I looked back and noticed one of her straps was twisted. I must have missed it so I pulled over to fix it. SO sucks at car seats. I'm always yelling at him to fix her
