I have fears about Mason hating being RFing too. He is a big, long boy. I hope he's fine with it.. but if not, oh well. The way I personally see it is this.. as an infant, he HATED it. He cried being strapped in, he cried being placed in, and would cry until the car 'rocked' him to sleep. Because he was colicky I'm actually pretty good at selective hearing and ignoring him if I need to, such as in a car when I'm driving. I didn't take him out of it just because he didn't like it. No way. So I see this as the same. I didn't at first, but after I started watching the crash tests and reading about it.. everyone thinks that it couldn't happen to them, but things do happen. And in the event that my baby was killed or paralyzed because he wasn't rear facing, I'd be *glad* to go back and hear his screaming, just to hear it, instead of him being dead, you know? IF he REALLY hates it, I might consider switching earlier than I'd like to, but I know now that I won't switch him at 1 year/20lbs. I'm a safe driver. I can't guarantee everyone else is. It is just remembering that driving is the most dangerous thing we do all day long.
