The ergo, CC etc actually help hip bubs! When DD was diagnosed, we were wearing her in the ergo and the ortho asked if we often used it and we said yes, and she said she could tell because although dd's socket was almost non exsistant, the joint had been kept close by the position the CC and ergo had kept her in It's super easy to wear them in either, as the position required is the froggy position which the DBB keeps them in already. I have both and lobe love them.
Ahh cool. Sounds like your DD's socket is much like my DD's was. Feeling comfortable about the CC now.

Thanks everyone, I'm feeling pretty good about splashing out and getting one. Now to decide on colour....
