What parenting products are worth buying used vs new?

Best rule: buy used for durable, easy-to-clean items; buy new for anything tied to crash safety, sleep safety, or hygiene.

Best to buy used

• Strollers: often a great secondhand buy if wheels, brakes, harness, and folding parts work well.
• Baby carriers/wraps: fine used if fabric, buckles, and stitching are intact.
• Baby clothes: one of the smartest used buys; babies outgrow them fast.
• Sturdy furniture: dressers, bookshelves, and other solid nursery pieces can save a lot.
• Durable toys: good if they clean easily and have no missing parts.

Best to buy new

• Car seats: safest new unless you know the full history, no crash, no recalls, no expiration.
• Crib mattresses: buy new for firmness, cleanliness, and safety.
• Breast pumps: new is the safest default for personal-use models.
• Pacifiers and bottle nipples: inexpensive, and hygiene matters.

Quick rule
If it protects your baby in a crash, is part of sleep setup, or touches milk/saliva, buy new. If it’s fabric-based, washable, and not safety-critical, used is usually a good value.

Before buying used, check recalls, damage, missing parts, odors, mold, and dates/expiration where relevant.
