The Manduca carrier's okay, many people do not know is that the optimal spread-squat-attitude (SAH) only at a certain dress size (about 74-80) is given. Younger children are perfectly straddles the stretcher and with larger legs hanging down. This is due to the non-adjustable bridge, because the bridge is sewn on the waist belt. Furthermore, unfortunately the support has no sling fabric on the back part of what causes the back which is so important for babies rounding can not take. Also, the supplied "neonatal use" makes the whole no better. It fits halt just a certain size. If the child has the right size, the Manduca is also great. Very comfortable for the wearer because the straps are nicely padded. Those who want to contribute from the outset, should make absolutely sure that the web-adjustable and the rear part of sling fabric is. Alternatives to Manduca (and also to the ERGObaby Carrier) would Mei Tais (Miss Pretty, HopTye, DidyTai etc) or other Fullbuckle Carrying (Carrying Aids who only buckles as the Manduca ... so the Emei baby who Buzzidil etc ). They are priced at the same, but you can carry his child so long :)
