Choosing the right baby bottle size depends on your baby's age and feeding needs. Newborns often start with smaller bottles (around 4 oz), while older babies may need larger bottles (8-11 oz) as their appetite grows. Consider how much your baby typically drinks in one feeding and if you want to minimize refills. Many parents find it helpful to have a mix of sizes on hand for different feeding situations. Always check the product details for age recommendations and features that suit your baby's stage.

To clean baby bottles, start by rinsing them with warm water right after use.

• Disassemble all parts, including nipples and rings.
• Wash each piece with hot, soapy water using a bottle brush to reach inside.
• Rinse thoroughly to remove any soap residue.
• Let all parts air dry on a clean rack.

Many baby bottles are designed with newborn safety in mind, including features like BPA-free materials and slow-flow nipples. Always review the product description for age recommendations and safety certifications. If you have specific concerns about materials or bottle shape, consult your pediatrician for guidance. Walmart offers a variety of bottles suitable for newborns, so you can find options that align with your preferences and your baby's needs.

Most baby bottles are versatile and can be used for both formula and expressed breast milk. Look for bottles with leak-resistant lids and clear measurement markings to help with accurate preparation. Some bottles are designed to reduce air intake, which can be helpful for both types of feeding. Always follow the manufacturer's instructions for cleaning and storage, especially when switching between formula and breast milk to maintain hygiene.

Some baby bottle packs include extra nipples, while others offer them separately. Check the product details to see what's included in the package. If you need replacements or want different flow rates as your baby grows, Walmart carries a range of compatible nipples and accessories. Having spare nipples on hand can be helpful in case of wear or for adjusting to your baby's changing feeding needs.
