When I was pregnant, my sister-in-law and my sister both could not stop talking about their carriers. I didn’t know what it was at the time, but both of them had Ergo carriers. I ended up with one and I was hooked. “The front pack” as we called it, went everywhere with us.
I would use it at Disneyland and be able to outrun (and avoid stress better than) any stroller using parent.
