This set includes two BabyGo silicone nipples designed for a comfortable and natural feeding experience. The size 6 designation indicates that these nipples are suitable for older infants, usually around the age of 6 months and up, accommodating the increased feeding needs as your child grows. The visible features include a clear, soft silicone material that mimics the flexibility and feel of a natural breast, supporting a smooth transition from breast to bottle. The packaging suggests that these nipples are easy to clean, likely free of BPA, and are designed with a baby's health and safety in mind. The product is secured in a plastic blister pack with a cardboard backing that highlights the product features and quality assurances to appeal to health-conscious parents.
