Common accessories included in sets are extra nipples in multiple flow levels, caps or storage/travel caps, pacifiers, a formula dispenser, and cleaning tools such as a bottle brush.
Suggested ages range from preemie/newborn (0–3 months) to broader spans like 0–36 months. Some items are labeled for 6 months+ or 12 months+, depending on the product.
Straw cups include soft weighted straws so babies can tip and sip from any angle, removable easy‑grip handles to teach holding, and sliding caps that keep the straw clean and help make the cup spill‑proof when closed.
Available nipple levels include Preemie/Level 0 (slowest) and Level 1 (Slow Flow), with some sets also offering Level 2, Level 3 and Level 4. Descriptions in product details commonly use terms like Slow, Medium, Medium‑Fast and Fast.
