Recommended positioning for baby
The first 6 months are critical in the spine and hip development of a baby. Supporting baby in a spread-squat position, whether in-arms, or in a carrier with baby’s arms and legs free or swaddled, favours healthy development of the hip joint.
Baby’s spinal column needs to be supported in a c-shaped curve while he is worn in an upright position in order to promote normal spine development. The legs will be in a spread-squat position, with the pelvis tilted forward and knees higher than the bum, forming an M shape, in order to maintain the spine in its c-shaped curve.
When baby is seated upright, his bum and his legs up to the knees are supported by the wearer’s body. The head will naturally lean forward, since the back is curved in a c-shape. Thus, a newborn with little tonus who is placed in a spread-squat position will have the freedom to move his head and legs, strengthening them in the process.
When the legs and pelvis are not accommodated in a spread-squat position, there can be a compression of blood vessels leading to impaired circulation in the legs.
When the hip joint is in extension, a lack of support to the legs can lead to a dislocation of the head of the femur with the hip socket, with the head of the femur coming out slightly from the hip socket. This will aggravate any existing hip dysplasia.
The spinal column lacks support and stability when the hips are not in flexion and the pelvis is tilted downwards. Not only is the spine not in a c-shaped curve, but it may be forced to arch back abnormally. Baby’s weight alone can be enough to cause compression and deformity at the base of the spine, which is mainly cartilage at this point.
Impact of improper positioning on the comfort of the wearer: A baby that is not worn in a spread-squat position will have its centre of gravity shifted away from the wearer. This increased tension on the lower part of the body generates additional strain on the shoulders of the wearer.
A baby worn in the physiologic M position favours healthy joint development, good circulation and ensures comfort for both baby and wearer.
