Re: Help me decide
I have never tried a babyhawk, but have a different mei tai. Sometimes I like a SSC (BBII) over a mei tai as they can be a little faster for me. I like the BBII or other SSC best for when I'm out and about so I don't have to deal with long straps hanging on the ground when out and about. I also tend to prefer a structured waist for longer term use as I feel it helps distribute the weight of the baby to my hips and away from my shoulders better.
That said, there are others out there who prefer a mei tai over a SSC any day. It's just a matter of personal preference.
