We have tried them all, the Moby - too hard when dealing with a screaming baby, the Bjorn - is a crotch dangler, not good for spine development, the Ergo - bulky and expensive. Then we came across the perfect carrier. It is compact, folds into a small square when not in used (easy storage in the diaper bag), it's comfortable, and flexible (carry your baby on your back, facing you - tummy to tummy and forward facing). One size fits all! Good for when baby's about 3 or 4 months old and has good head control to about 30 pounds. The straps are wide and the weight of the baby is distributed across your back. Available only in the Special Edition print for now.
