Using your Cry Babies Tiny Cuddles Mermaid Doll - Delphine is easy. First, fill her with water. When you want to see her cry real tears, just press on her head. She's great for cuddling and playing with. When taking her out, since she's lightweight, you can easily carry her in a small bag. For maintenance, keep her away from sharp objects to avoid tearing the soft fabric of her mermaid tail. After play, dry her if she gets wet. Make sure to store her in a clean and dry place. Remember, this doll is recommended for children ages 18+ months, so adult supervision is a good idea during playtime.
