Quick answer
Wash baby blankets and quilts in cold water on a gentle or delicate cycle with mild detergent, then air-dry or tumble on low heat. Avoid hot water, high dryer heat, and fabric softener, which cause shrinking and break down cotton fibers. For specific items like a cotton muslin lovey or a quilted muslin blanket, always check the care label and treat the fabric as you would a delicate garment.
Why baby blankets shrink and how to prevent it
Shrinking happens when cotton fibers are exposed to heat and agitation. Hot water opens the fibers, and high heat in the dryer causes them to contract. To prevent shrinking, use cold water (below 30°C/86°F) and a gentle cycle. If you must use warm water for stains, choose the coolest setting that works and avoid sudden temperature changes. Drying is the bigger culprit: high heat can shrink a cotton blanket by several inches. Air-drying flat or on a line is safest, but if you use a dryer, select the lowest heat setting and remove the item while slightly damp.
Step-by-step washing instructions for muslin and quilted blankets
Start by checking the care label. For cotton muslin items like a lovey or sleep sack, machine wash cold on a gentle cycle with a small amount of mild, fragrance-free detergent. Avoid bleach and fabric softener, which can coat fibers and reduce breathability. If the blanket has a quilted layer, wash it separately from items with zippers or hooks to prevent snags. For quilts with decorative trim, turn them inside out or place them in a mesh laundry bag. After washing, gently reshape the blanket and lay it flat to dry on a clean towel. If you use a dryer, tumble dry low and check frequently; remove while slightly damp and smooth by hand.
How to fix a baby blanket that already shrank
If a cotton blanket has shrunk slightly, you can sometimes relax the fibers by soaking it in cool water with a capful of hair conditioner or a fabric relaxer for 15 minutes. Gently stretch the blanket back to shape while wet, then lay it flat to dry. Do not wring or twist. This method works best on minor shrinkage (up to 5%) and may not restore a heavily felted blanket. For quilts with batting, stretching can distort the layers, so it’s safer to accept the new size or repurpose the quilt as a play mat or doll blanket.

Diagnosis: common blanket laundry problems and fixes
- Blanket feels stiff after washing: Likely cause: detergent residue or hard water minerals. Corrective action: rewash with a small amount of mild detergent and add 1/2 cup white vinegar to the rinse cycle. Stop if stiffness persists after two attempts; the fabric may have been damaged by heat. Vinegar rinse restores softness without chemicals.
- Blanket shrank after drying: Likely cause: high dryer heat. Corrective action: soak in cool water with hair conditioner, stretch gently, and air-dry flat. This works for minor shrinkage. If the blanket has shrunk more than 10% or the quilt batting is distorted, choose another option: use it as a play mat or donate it. Prevention is easier than repair; always air-dry or use low heat.
- Colors faded or bled: Likely cause: washing with hot water or mixing with non-colorfast items. Corrective action: wash separately in cold water with a color catcher sheet. If fading is severe, the blanket may no longer be suitable for sleep; repurpose it for supervised play. Wash new blankets separately for the first few washes.
Product care details
- Lovey Animal Security Blankets: Made with 100% cotton muslin and pre-washed for softness. Pre-washed muslin is less likely to shrink further if you follow cold-water washing and low-heat drying.
- Classic Quilt: Crafted from three layers of premium cotton muslin with color-coordinating trim. The quilted layers require gentle washing to avoid shifting or bunching; always use a gentle cycle and avoid hot water.
- Muslin Sleep Sack: 1.0 TOG cotton sleep sack, sleeveless design. Cotton sleep sacks should be washed cold and air-dried to maintain fit and breathability; high heat can shrink the fabric and affect the TOG rating.
