I bought an Ergo, but am now wondering about the diaper bag. I imagine that a backpack diaper bag is more comfortable/practical than any other type, but I don't like the look of the backpack made by Ergo (seems to flimsy, no insulation).
The Alpha Sherpa gets great reviews, but the features that make it ergonomically comfortable (sternum and waist belts) don't appear to be compatible w/ an Ergo.
What do others do? I need to babywear for long urban treks, but need my hands free.
