A friend of mine just asked me a question, and I had no idea what to tell her... I thought I'd ask you all if you knew anything. She overheard a conversation in which somebody who is anti-stroller for her infant was asked why. Apparently the anti-stroller/babywearer went on at length about childhood obesity. My friend couldn't figure out what the link between the two was (given that the infant was young--it's not like the option was a stroller or walking). The only thing I could come up with was that it might facilitate breastfeeding (and therefore make obesity less likely). That seems like a bit of a stretch, though. Is there some research that I'm missing?
