I stopped trying unless I am asked. a few weeks ago on another board someone asked if they could turn their 11 mo old yet because "Her feet are all squished touching the back now".
a lot of people replied that she could and they turned their kids at 1 year or just before for the same reason.
I posted about erf and said how I had turned my dd at 1 year, but turned her back at 2 and she'll stay that way longer. I said it's safer (but didn't say why) and said I'd be happy to post links if anyone was interested.
Someone wanted the links, so I posted them all, even the story about the girl who was in an accident ff and the article clearly says her injuries would be much less severe had she been RF and she was still small enough that she could have been.
Much to my excitment, 2 other ladies there said they also ERF, I was so glad because then I was not the only "psycho" who does that. There weren't many replies after the ERF comments from the 3 of us, but one lady said she's considering doing that with her baby. No one said anything negative about ERF, I think either they just didn't have anything to say or they realized we were right.
Either way, I still dont bring it up unless I am asked. But I have my signature pic at all the boards I go to, its the same one that I have here. I use it on purpose so people will see it and maybe ask me why I have Hannah RF still so I will have the opportunity to talk about it.
