Experts say that when a baby moves, the expansion and contraction of the abdomen and side waist can vary by as much as 20%.
The waistband non woven of the diaper keeps your baby comfortable without sagging and leaking urine. 
If the waistline of the diaper is unreasonably designed, it will strangle the baby, making it difficult to move freely, and it will make breathing difficult.
