I have a huge (15lbs) 10-week-old baby. He really, really wants to face forward, as in throws a fit until he's turned around on lap or in carrier, after which he is completely happy. I used a Bjorn with my 1st 9 years ago before I know about the supposed hip issues and it was great. Now though I don't feel comfortable using it...though I have tried a couple of times and indeed, my new little guy looked happier than in any other carrier.
I've used a Moby wrap a few times and that worked well until he got so big -- now it just kills my back. Regular ring sling has not been great as he is not developmentally able to hold himself up well for a hip carry yet and he's so big he just seems squashed in other carries (and also he just hasn't liked it very much). Maybe I am just not doing it right.
I just don't buy the "overstimulation" argument about not using front carriers -- that just seems silly to me. However, the hip/crotch thing does make sense.
So I'd love to find a front-facing carrier that was supportive like an Ergo. Does such a thing exist? Is the Belle baby carrier any good?
