On a good day, obtaining diapers or feminine hygiene products can be a struggle for people in need. For many whose lives have been ravaged by Hurricane Harvey, not having those items is now its own crisis.

Since the storm slammed into Texas on Friday, tens of thousands of people have been displaced. Those who were able to pack a few supplies are running low. Others couldnt grab a stash of tampons or diapers as they fled the rising water.

These products are often not provided at emergency shelters. While relief groups work to bring essentials to the victims, many of the main humanitarian groups dont supply menstrual products or diapers.

Its not something that families, especially when theyre coming to a shelter, that they pack up and bring with them, Jorge Medina, executive director of the Texas Diaper Bank , told NPR about the need for diapers. And then while theyre at the shelter, whatever they did bring, they run out.
