I really wan to re-rearface my daughter as well, but my husband is resisting. In fact, I just wrote a blog on it. I'd really appreciate any comments on there promoting my decision so I could show my husband that I'm not crazy.
Thanks!

And I wouldn't even have asked my husband. I'd just flip her and state, "I flipped her back, she still fits and she's safest". He knows I did all the RF research and he knows he married an intelligent woman that wouldn't be doing it unless her research and facts showed it to be a safe thing to do. In fact, I'd be a little offended if he doubted me. If he had concerns, I'd expect him to go and do the research on his own without involving me and then he'd come to the same conclusion I did, and all would be well.
I'm not sure if your husband is doubting it's safer for her, or if he really truly thinks it she'd resist (like your blog mentioned)? If it the latter, then I'm not sure why he just wouldn't allow her to be flipped, and if it caused an issue, then you guys can always flip her back. If he's not willing to try, it seems to me like he must have other concerns? Since she's already FF, maybe you could tell him that since you've already done all the research, you'll give him a week to do his own research to show that RF would not be safe for her. If he can prove that, then you'll keep her FF. If he can't or doesn't do the research, then back RF she goes.
