- Wash on cold | Gentle cycle inside out.
- Lay flat to dry for best results | Tumble dry low and use a cool iron if needed.
- Always follow the care tag.
- Our viscose fabric is super soft, and with that softness, some pilling is normal.
- Flat drying helps keep the fabric smooth and colors vibrant.
* Please Note:
- Do not wash with items that have zippers, buttons, or rough hardware — it can snag the fabric.
- Wash separately with other baby clothing for best care.
