This wide mouthed threaded nipple is designed for comfortable sucking for babies. The pacifier is made of high-quality and safe silicone material, with a soft texture that will not harm the baby's delicate mouth. It strictly meets the safety standards for baby products, and parents can rest assured. The wide mouth design simulates the baby's oral milk holding state during breastfeeding, fits the oral structure, allows the baby to naturally and comfortably suck, reduces air intake, and lowers the risk of spitting and choking on milk. The threaded part is finely crafted, tightly fitting with the bottle, easy to install and disassemble, and tightly sewn to prevent milk leakage. Whether it's daily feeding or when the baby goes out, it can provide a stable and comfortable sucking experience for the baby, making it a caring partner on the baby's growth journey.
