On this page, you’ll see a few main styles to choose from:

• Natural-shaped nipples: Designed to support a familiar latch and release milk as baby actively drinks, which can feel more like nursing.
• Vented bottles: Include an internal vent system to help keep the nipple filled, which can reduce how much air baby swallows.
• Materials: Options include clear glass for durability and clarity, and lightweight plastics like PP or PPSU (a heat‑resistant, sturdy plastic). All are labeled BPA free.
• Sizes: Small (2–4 oz) for early feeds, mid (8–9 oz) for growing appetites, and larger (11 oz) for bigger feeds.
• Bundles & designs: Newborn gift sets, multipacks, and fun prints.

Check each product page for exact features and what’s included.

The “best” style varies by baby. A few tips can help you narrow it down:

• If you’re combo feeding: A wider, breast‑shaped nipple that pauses between sips can make switching between breast and bottle feel more natural.
• If baby swallows air: Look for bottles with an internal vent that keeps the nipple filled to support a smoother drinking pace.
• Easy cleaning: Wide‑neck bottles with fewer parts and dishwasher‑safe markings can be helpful.
• Weight & feel: Glass offers clarity and scratch resistance; plastic or PPSU feels lighter for on‑the‑go.
• Flow control: Start with newborn/slow flow; move up only if feeds take too long or baby compresses the nipple.

Since every baby is different, starting with a small pack can be a practical way to test what works. Pickup and delivery on Walmart.com can make trying options easier.

Smaller sizes are usually easier for early feeds and reduce waste as baby’s intake changes.

• 2 oz: Handy for the first days, supplements, or paced feeds.
• 4 oz: A common go‑to throughout the newborn stage.
• 8–9 oz: Useful as appetite grows over the next months.
• 11 oz: Typically for older babies with larger single feeds.

Every baby’s needs differ, so follow your care provider’s guidance on volumes and feeding frequency. It can be helpful to start with a few small bottles, then add larger sizes as needed. You’ll find a range of sizes and multipacks on Walmart.com, with pickup and delivery options for convenience.

A collapsing or leaking nipple can happen for a few reasons:

• Flow may be too slow: If baby sucks hard and the nipple compresses, consider the next flow level (check age/flow info on the package).
• Assembly issues: Make sure all parts are fully seated. For vented bottles, align the vent per the instructions so air can enter the bottle.
• Overtightening: If the collar is too tight, it can block airflow and cause collapsing—or too loose can allow leaks.
• Wear and tear: Replace nipples showing thinning, cracking, stickiness, or swelling.
• Clogging: Avoid thickened liquids not suited for the nipple; never enlarge holes yourself.

These checks can help improve performance, but results vary by feeding style and conditions. Refer to the product’s manual for assembly specifics.

Before first use, sterilize. For daily care, a simple routine can help:

1. Disassemble completely: Separate bottle, nipple, ring, cap, and any vent pieces.
2. Wash: Use warm, soapy water and a bottle brush, or the top rack of the dishwasher if the item is marked dishwasher safe.
3. Rinse & dry: Rinse thoroughly and air‑dry on a clean rack; avoid towel drying to reduce lint transfer.
4. Sterilize periodically: Boiling, electric steam sterilizers, or microwave sterilizer bags can be used if the product is compatible—check the item page/manual.
5. Inspect parts: Replace any that become cloudy, cracked, or sticky.

You can find compatible brushes, drying racks, and replacement nipples and rings on Walmart.com. Always follow the care instructions provided with your specific bottle.
