Manduca and Hip displaysia

[Miss.September]

Found this on an official manduca site --

This position is frequently referred to as a ‘frog’ position, and in medical jargon is often described by means of exact angles. We prefer our own term, the 'M position', as we think it helps the non-expert to visualise very well what it is supposed to look like: in this position, the lower legs, the thighs and the bottom all together look rather like a capital M. Babywearing in this position can help prevent hip dysplasias and encourages the baby’s still immature hip sockets to develop in the way nature intended.

Agreed - We have a ergo, and yes, they position babies/toddlers in the same position as a manduca. I did my research pre purchase as DS was a Hip dysplasia bub so there was no way I was taking any risks with DD. These types of carriers that position bubs in a frog type sitting position actually discourage hip problems rather than cause them so your friend is quite misinformed here.
I would not however use a baby born etc that lets the legs dangle as mentioned as these would not be good for hip development at all.
