How to Wash Baby Pajamas So They Last

Baby pajamas go through the wash more often than anything else your child wears. A few habits keep them soft, keep their size and keep flame-resistant fabric working as it should.

The basics

  1. Close zips and snaps. Open zips snag other clothes and wear out faster.
  2. Turn them inside out. That protects prints and the soft face of the fabric.
  3. Wash cool or warm, not hot. Hot water is the main cause of shrinking, especially for cotton and rayon.
  4. Dry low or hang. A hot dryer shrinks fabric and wears out elastic cuffs.

By fabric

  • Cotton: warm wash, low dry. Expect a little shrinking after the first wash.
  • Fleece and polyester: cool wash, low dry, no fabric softener, which can mat the surface.
  • Flame-resistant fabric: follow the label. Skip softener and bleach unless the label allows them.
  • Rayon made from bamboo: cool, gentle wash and low heat or air dry.
