Baby Bottles

Glass and stainless steel are durable and resist staining; BPA-free plastics are lightweight but may wear over time. All materials can be cleaned by hand or in a sterilizer; check manufacturer instructions for high-heat tolerance

Venting systems can reduce swallowed air and may help with gas and spit-up for some infants, but effectiveness varies by baby; consider a bottle with a proven vent if your baby shows signs of colic or excessive gas

Yes — not all nipples fit every bottle brand, and some breast pump kits only connect directly to specific bottle designs; verify compatibility or look for universal adapter options if you plan to pump directly into bottles

Expect to pay from budget options under $20 for basic bottles to $40–$60 for higher-end sets or specialty bottles, with an average price around the low tens; factor in replacement nipples and extras when estimating cost

Replace nipples at the first sign of wear, thinning, or cracking, typically every 2–3 months with regular use; bottles should be replaced if damaged, discolored, or after long-term wear to maintain hygiene and function

Rinse parts immediately after use, wash thoroughly with warm soapy water or in the top rack of a dishwasher if parts are dishwasher-safe, and sterilize by boiling, steam sterilizer, or microwave sterilizer according to manufacturer guidelines
