Reasons against those methods:

• The supporting cloth between the legs cannot be pulled wide enough, so the spread-squat position is not possible.
  
  
• The back is not supported properly because it is being pressed against the stomach/chest of the carrier. (Danger of hollow position!)
  
  
• The baby’s head is not supported correctly either.
  
  
• The baby can "look" forward, but the many impressions caused by this can cause overstimulation.
  
  
• The baby is sitting on the lowest point of the upper body, so boys are then subject to pressure against the testicles.
