I don't have any recent pictures of her with the blankets in. I think we took them out shortly after that picture was taken. I have a couple of pictures from the other day, that show the True Fit with no infant padding but we did try the headrest in. However, I've since taken the headrest out. As April said, it wasn't a good fit so we haven't had it in, and I tried it again for a day to see and still didn't love it. It didn't actually push her head forward any more, but because of where the harness straps come out it sat really low and just didn't do much. We took out the infant padding because the crotch buckle was getting tight with it in, and I thought the head padding might provide a little extra support.
Funny about the torticollis (not funny haha of course), we were a little worried that our baby might be getting it. She would only look one direction while being worn and was really fussy nursing on one side. It's never progressed though. She still prefers looking one direction while worn, but now I think that side of the carrier must just taste better or something.
There is lots of room in the True Fit to put blankets for support.
About the Radian, my older daughter didn't really have anywhere to put her head and she kept waking herself up as her head fell when she fell asleep. Then I found out you can put the infant support in as head support, and it's actually a really nice support. She tells me it's very comfy and if I've swung it out she will ask us to stick it back in for her. You can see it in the pictures too.
Both pictures were taken the same day, the first was like 7 o'clock in the morning (which is why my older daughter looks like she just woke up, she did), and the second was after my older daughter had a really minor surgery and we bought the food the doctor "prescribed". They didn't actually hold those things they're both holding for the drive, it was just for a picture.
