Signs it's time to...

Title

Size up

  • Waist sits more than 2 fingers below the belly button
  • Tabs barely close at the edges of the landing zone
  • Leaves lasting red marks or indents on the waist and thighs
  • You experience an increase in leaks, blowouts, and tears, especially overnight
Title

Size down

  • Sags around the legs, leading to leaks
  • Gaps at the waist and/or bunched up leg holes
  • Tabs close together or overlap (except on sizes N and 1 where we’ve added overlapping tabs as a feature to give smaller babies a comfortable, customizable fit)
