It is healthy for a baby's back to be rounded!
The baby is born in a rounded position. This is caused by the splayed "frog" position. The spine straightens in three stages, taking about one year. This straightening starts at the top, at the cervical vertebrae, and progresses down. Lying on her stomach, the child can lift her head, hold it up, turn it, etc. Later the child also do this lying on his or her back. This means the seven cervical vertebrae are completely straightened (cervical lordosis).
Then, the child strengthens the flexor and extensor muscles in its body (flexor muscles in the chest and stomach, extensor muscles in the buttocks and pelvic area). Gradually, the whole central part of the spine with the twelve thoracic vertebrae straightens (thoracic kyphosis). This straightening is completed when the child can sit up on its own.
Finally, the five lumbar vertebrae straighten (lumbar lordosis). When the child can walk alone, this stage has been completed and its spine is fully straightened.
This knowledge about spinal development results in the following requirements for the ideal sling.
- The sling must be supple, but at the same time support the child firmly and steadily.
- It must enclose the baby's body like a firm bandage, and should be tied in such a way that it absorbs the wearer's movements and jolts.
- It should be tied in such a way that it absorbs the wearer's movements and jolts, carrying them away from the child's spine, back to the wearer.
This protects the child´s delicate vertebrae and vertebral discs.
Particular attention must be paid to the "frog" position, as this produces both a healthy back and healthy development of the hip joints, which are still cartilaginous.
