Carriers like HAB, Close, Ergo are great for bubs with hip issues as they hold legs in similar position to brace. Bjorn one not so good,(Bellybelly posted a pic on FB today). I used a HAB with DD while in a brace no problem, and is more comfy would think as not lying on bar. I also used Ergo, close carrier was not really around when had DD so never looked. HAB I like wearing it but can be an issue getting on and off as need to remember how to tie not drop ends in puddles etc. if had my time again would just by HAB style from a SAHM (will PM you link) as is just a piece of material. They ate good to get before birth in my opinion so can practice tying etc (I used kermit).
