I am the more forceful kind so when I say so it is so...LOL. But yes, everybody who doesn't know abt the truth of babywearing will think that way. U have to educate them with articles and pictures. Ur mil is really stuck in the mud. It's a carrier for goodness sake, not some forceful hip expander w the adult body being a forceful expander. Moreover, baby don't spend much time in there - usually at most 1-2 hrs caz u will be tired, baby need to change diaper or something. How is something that is only for a short time a couple of times a day or maybe just once a day going to drastically affect the body as compared to the rest of the 20+hrs when not in carrier? Really nonsense I must say. I would just use the Tula. My baby. My parenting style.
