Moby wrap: legs in or out?

I have a 7 week old who LOVES being in the Moby wrap. We have been using the newborn hug hold, but I recently came across something saying "froggy legs" are no longer recommended for hip development.  I came across this site with some videos, so I tried the legs out method today. My daughter seemed to really like it. http://bwisomd.org/stretchy-wrap-tutorials-and-tips/
