biberones avent 4 oz

Many reviewers report that Avent glass bottles work with a range of breast pumps and third‑party wide/balance nipples. However, some users noted occasional nipple‑fit and cover‑compatibility issues. Compatibility can vary by pump model and third‑party nipple design, so check the specific pump and nipple dimensions for a final fit confirmation.

The bottles use borosilicate glass for the body and silicone for the nipple. The glass is described as BPA‑free.

Options include single 4 oz bottles (package quantity 1) and multi‑bottle sets that combine 4 oz and 8 oz bottles—for example, sets listing three 4 oz and two 8 oz bottles.

Suggested ages vary by product listing. For example, a single 4 oz listing is shown as 0–3 months, while a multi‑bottle set is listed as suitable from 0–12 months. Check the specific product details for the listing you’re considering.
