Why Am I Getting Leaks?

The following are causes for leaks:

  • There is a fit problem, either gaping in the leg holes, or at the front at the top of the nappy.
  • The nappy needs more absorption. If the inserts are saturated, then more absorption is needed. e.g. generally one insert will not last 3 hours.
    A child changes feeding habits significantly from birth to toddlerhood. At birth the primary source of food is liquid, therefore it is expected that output will be similar. As a child gets older, they are able to hold their bladder and therefore can flood a nappy, in some situations the absorbency cannot keep up with that amount of liquid. Both situations require more absorption. See Adding Absorbency for options.
  • The nappy needs to be changed more frequently, unless they are night nappies, most cloth nappies will only last 2 hours max before needing to be changed.
  • The microfiber insert is saturated and compression is causing the liquid to seep.
  • Have the inserts been prepped? New inserts absorb less than older ones.
    The surface area of the fibers increases over time with washing (ie friction), the fibers become looser and micro piling occurs. The greater the surface area, the more absorbency potential.
    Cotton, hemp and bamboo will continue building absorbency with use, change more frequently during this time. See New Nappies for more info.
  • If the PUL has delaminated, cracked or otherwise become damaged, it will mean moisture will seep through from the inserts.
  • Another less seen cause is that the inserts are repelling water, which is due to using soap in the washing machine. See Detergents That Contain No Surfactants page for more info.
