Due to ´squatting' you bring your baby into the correct ergonomical spread-squat-position:
For this purpose you slide the knees gently upwards towards the abdomen.
This tilts the pelvis automatically, the back is rounded slightly, the back and the still soft intervertebral discs are relieved.
Squatting is very important, especially for newborns!
If you squat your baby correctly, its knees are higher than the buttocks, the legs spread apart slightly and the back is rounded.
You should check the stance in a mirror in the beginning.
