My 13 week old DD has been put into a Pavlik harness for DDH :( www.hip-baby.org/pavlik.html In case you're not familiar with it, her legs are bent at the knee and as far out as they can go - there's a picture at the link above. The ultimate no-no is to have her legs come together because the whole point is that her legs stay apart the whole time.
The consultant assured me there would be no problems breast feeding, but had no practical advice on how, nor did the young physio who also said it was easy but ruled out her lying on her side in any way for the duration of the feed. 
We're finding it difficult to do on one side without putting pressure on her 'bad' leg. She mostly fed lying down previously, which is now possible on one side only. We've tried the cradle hold which can sort of work if I suspend her so that there is no pressure on that leg, but it is murder on the arms & she seems to get restless after a few minutes. She screamed when I tried the rugby hold, so guessing that's out too. Any suggestions?
Last night was miserable for all three of us as she was uncomfortable, and though she's fed since the harness has been on, her feeds are a lot shorter and I suspect she's only feeding enough to get by. I'm so worried that she's not getting enough to grow. :( :(
