  • The diaper starts to leak
  • You’re changing their diaper more
  • If the tabs no longer stretch enough to fasten comfortably over the hip
  • The diaper feels tight around the waistband, leg cuffs or is starting to leave red marks on their skin
  • You can’t run a finger inside the waistband when fastened
