Cloth pads are very absorbent and are designed to contain effectively outflow. We do recommend changing to suit your needs to reduce the chance of leaks, recommended changing time between 2-4 hours.  The organic cotton is carried over to the wings for optimum protection.  Please avoid fabric softener on your pads, as this can create a build-up in the fabric and reduce absorbency.  If you are finding your pad is not effectively containing your flow, you will need to consider upgrading to one of our larger pad options.
