Baby Bottle Usage Specifications

When selecting a baby bottle, priority should be given to material safety. The mainstream materials are divided into three types: glass, food-grade silicone, and PPSU. Glass bottles are high-temperature resistant, easy to clean, and free of chemical residues, suitable for newborns and boiling disinfection scenarios, but need to be protected from falling. Silicone bottles are soft, skin-friendly, lightweight, and shatterproof, suitable for babies to grasp independently; choose food-grade silicone with no odor and good elasticity. PPSU bottles combine the advantages of high temperature resistance, shatter resistance, and light weight, with stable material that is not easy to age, making them a cost-effective choice. Avoid purchasing PC material (which carries the risk of containing bisphenol A).

The nipple should match the baby's age. Newborns should use round-hole nipples with slow flow rate; after 3 months old, cross-hole or Y-hole nipples can be replaced according to the baby's eating situation. Prioritize medical silicone for the nipple material, ensuring it is soft, tough, and free of burrs to prevent the baby from choking or damaging the oral cavity while sucking. Meanwhile, check the bottle's sealing performance—only select it if there is no leakage when tightened and inverted.

New bottles must be thoroughly disinfected before use to remove residual dust and odor from the production process. After daily use, immediately disassemble the bottle, nipple, straw, sealing ring and other components, and use a special bottle brush to remove milk stains and dirt in gaps on the inner wall to avoid bacterial growth due to milk scale accumulation.

Boiling disinfection is the preferred method: put the disassembled components into boiling water—glass bottles can be put directly in, while silicone and PPSU bottles should be put in after the water boils. Control the boiling time at 5-10 minutes to prevent component deformation. A steam sterilizer can also be used according to the instruction manual. After disinfection, air-dry naturally or wipe with sterile gauze, and store in a dry, clean sealed container to avoid secondary pollution. Disinfect after each use, and disinfect new bottles twice before the first use.

Before preparing milk powder, parents should wash their hands thoroughly and prepare disinfected bottles, nipples, and warm water. Control the water temperature at 40-50℃—excessively high temperature will destroy nutrients in milk powder, while excessively low temperature makes it difficult to dissolve. Use a water thermometer for accurate measurement instead of judging by hand feel. Prepare milk strictly according to the ratio specified on the milk powder instructions: add water first, then milk powder, and shake the bottle to dissolve evenly. Do not rub vigorously to prevent excessive bubbles that cause baby bloating.

Maintain a correct posture during feeding: hold the baby obliquely at a 45° angle, and tilt the bottle so that the nipple is fully filled with milk, avoiding the baby inhaling air while sucking, which may cause spit-up and bloating. Closely observe the baby's condition during feeding; if choking occurs, stop feeding immediately and pat the baby's back gently to relieve it. Clean the bottle in a timely manner after feeding. Do not store leftover milk for a long time—it can be kept at room temperature for no more than 2 hours and in the refrigerator for no more than 24 hours. Reheat thoroughly to lukewarm before reuse, and do not reheat repeatedly.

Regularly check the condition of bottles and accessories. Immediately replace glass bottles if they have cracks or damage; promptly replace silicone and PPSU bottles if they show aging phenomena such as yellowing, hardening, or deformation. It is recommended to replace bottles every 3-6 months and nipples every 1-2 months. Regularly check the elasticity of the sealing ring; replace it in time if there is leakage or aging to avoid milk leakage or bacterial residue.

Avoid using detergents containing fragrances and chemical ingredients for cleaning; choose baby-specific bottle cleaners, and ensure no foam residue after rinsing. Store away from direct sunlight, high temperature, and humid environments to prevent material aging and deterioration.

In short, the use of baby bottles must adhere to the principle of "safety first, scientific standardization," and no link from selection to maintenance can be ignored. Standardized use of baby bottles can not only ensure the baby's food safety but also build a solid line of defense for the baby's healthy growth.
