A big collection event for the 10th annual March of Diapers Drive will run 10 a.m. to 2 p.m. Saturday, March 23, at Twin Lakes Fred Meyer.

The drive is hosted annually by local nonprofit Do The Right Thing, which distributes diapers as well as baby and adult hygiene products to nearly two dozen organizations and nonprofits across South King County.

Founder and organizer Cheryl Hurst said this year’s goal is to reach 500,000 diapers. Last year’s drive collected about 412,000 diapers.

The most in-demand sizes for diapers are sizes 5, 6 and 7. Also needed are baby wipes, toddler pull-ups and adult diapers.

Hurst said the diaper brand Luvs offers the most value for the price. The average diaper can cost between 17 cents and 30 cents each, and a child can go through several diapers a day. In addition, diapers are not covered by social assistance like WIC, EBT or food stamps, which can be a burden on families living in poverty, Hurst said.

“I could literally have a PhD in diapers,” said Hurst, laughing at how much she has learned about diapers and people’s needs during the past 10 years. “The drive has grown every year we’ve done it.”

This year marks Hurst’s final year at the helm of March of Diapers because she is moving out of state. There will still be an unofficial diaper bank in Federal Way with someone else managing it, she said.

Recipients of March of Diapers donations include DAWN (Domestic Abuse Women’s Network), Nourish Food Bank of Edgewood, Foster Champs, Maple Valley Food Bank, Care Net of Puget Sound, Fusion Transitional Housing, Pediatric Interim Care, Parent Child Assistance Program, Prepares of Washington, South King Food Bank at the Federal Way Senior Center, Children’s Home Society, Auburn Food Bank, Iraqi Community Center, We Love Our City Kent, Communities in Schools of Federal Way and Mother Africa.

Twin Lakes Fred Meyer, the site of this weekend’s collection, is located at 33702 21st Ave. SW.
