APPLE BABY  insulated steel baby sipper (400ml) with a rope is a specially designed water bottle aimed at keeping your baby's drinks at the desired temperature while ensuring ease of use and safety. Here are the key features and benefits of such a product:

Key Features:

1. Material:

   • The insulated steel construction ensures that the bottle is durable, rust-resistant, and free from harmful chemicals like BPA.
   • The bottle usually has a double-wall vacuum insulation that helps maintain the temperature of the liquid, keeping it cold or hot for several hours.

2. Capacity:

   • The 400ml capacity is ideal for babies and toddlers, providing enough liquid for them without being too heavy or difficult to handle. This size is typically suitable for water, milk, or juices.

3. Design & Functionality:

   • The spill-proof or leak-proof lid often features a sipper spout or a soft, easy-to-suck straw that is gentle on your baby’s gums and teeth.
   • Some versions may also have a non-slip base to prevent the bottle from tipping over when placed on a flat surface.
   • The insulated walls help maintain the drink's temperature, which is especially useful for parents who need to keep milk warm or juice cold while on the go.

4. Rope for Easy Carrying:

   • The rope or strap attached to the bottle allows you to easily carry the sipper or attach it to a diaper bag, backpack, or stroller. This feature makes it easy for parents to keep the sipper accessible at all times without worrying about it getting lost or misplaced.
   • The rope can also serve as an anti-drop feature, preventing the sipper from falling on the ground, especially when your baby is learning to hold it.

5. Child-Friendly Design:

   • The bottle is often designed with bright, engaging colors and cute characters (animals, cartoon characters, etc.) that appeal to children, encouraging them to drink more fluids.
   • Ergonomic handles may be included to help babies or toddlers hold the bottle easily and independently as they start to develop motor skills.

6. Safety & Durability:

   • Made from food-grade stainless steel, this bottle is BPA-free and non-toxic, ensuring that the drink remains safe for your baby.
   • The steel construction is sturdy and resistant to dents, scratches, and rust, ensuring long-lasting use even with daily handling.

7. Temperature Retention:

   • The insulation ensures that liquids remain at the ideal temperature for longer, which is especially useful when traveling or during outings where access to a refrigerator or hot water may be limited.

8. Easy to Clean:

   • The design usually allows for easy disassembly of the bottle for cleaning. Most insulated baby sippers are also dishwasher-safe, though it’s always best to verify care instructions from the manufacturer.
