Quick answer

Wash your Hatley bamboo sleeper in cold water on a gentle cycle and dry it on low heat or hang it to dry. Check the fit at the wrists, ankles, and chin guard before each wear, and size up when the zipper starts to pull or the cuffs leave marks.

Why bamboo sleepwear needs a gentler routine

Bamboo viscose is soft and breathable, but it can shrink or lose its smooth feel if you treat it like everyday cotton. Hot water and high dryer heat are the two biggest culprits. A cooler, slower routine protects the fabric and helps the sleeper keep its shape through repeated washes.

The Hatley sleeper also has a full-length zipper and a chin guard. Those details are what make diaper changes quick, but they need a little attention in the wash so the zipper tape doesn't warp and the guard stays flat against your baby's skin.

When to size up instead of stretching the fit

A bamboo sleeper should feel snug but not tight. If you notice red marks at the wrists or ankles, or the fabric pulls across the shoulders when your baby stretches, the sleeper is too small. Sizing up is better than trying to stretch the fabric, which can distort the zipper and reduce the sleeper's life.

Because bamboo can relax slightly with wear, judge the fit fresh out of the wash rather than at the end of the day. If it fits well then, it will stay comfortable as your baby moves.

Step-by-step care routine

  1. Prep the sleeper: Close the zipper completely and turn the sleeper inside out. Fasten any snaps or hook-and-loop tabs if present. This keeps the zipper teeth from catching on other clothes and protects the chin guard. A closed zipper also prevents the sleeper from twisting into a rope in the wash.
  2. Wash cold on gentle: Use a mild, dye-free detergent and select a cold-water gentle or delicate cycle. Avoid fabric softener and bleach, which can coat the bamboo fibers and reduce breathability. If your machine has a hand-wash cycle, that is even gentler on the viscose.
  3. Skip the heavy spin: Choose a low-spin or no-spin setting. High-speed spinning can stretch the fabric and stress the zipper seams. A slightly wetter sleeper is easier on the fabric than a high-speed spin.
  4. Dry low or hang: Tumble dry on low heat only, or hang the sleeper to dry. High heat is the fastest way to shrink bamboo viscose and make it feel stiff. If you hang dry, reshape the sleeper while damp so the zipper dries flat.
  5. Check the fit before each wear: With the sleeper on, check that the chin guard lies flat, the zipper doesn't pull, and the cuffs leave no red marks. If the sleeper is tight across the shoulders or short in the stride, move up a size. A well-fitting sleeper should allow a finger's width of room at the wrist and ankle.
