A mei tai (pronounced may die) is wonderful for long carries. The weight is distributed evenly with 2 shoulder straps. The mei tai can be used for front & back carries. It can be used for hip carries in a pinch, but it's not quite as comfortable. The mei tai carriers available at The Worn Baby have a body that is cinchable via drawstring and wide shoulder straps. This allows the mei tai to properly support small babies, then accommodate them as they grow.
