These bottles have been developed based on over 60 years of research into babies' natural sucking behavior. The upgraded Pigeon SofTouch Nursing Bottles feature a research-based latch-on line to facilitate appropriate latching, along with an even softer nipple designed to closely resemble the mother's breast. The design of the SofTouch Baby Bottles aims to mimic the feeding movements that babies perform when nursing, supporting breastfeeding mothers who may need to supplement with bottle feeding. Additionally, the bottles are anti-colic, equipped with an advanced air vent system to minimize the ingestion of air during feeding, promoting a more comfortable experience for the baby. The nipple of the bottle is round-cut, allowing milk to flow consistently and gradually, which is particularly beneficial for newborns who are still developing their sucking abilities. The SS size nipple included with the 200ml bottle is specially designed for newborn babies, ensuring a comfortable and natural feeding experience. Overall, the Pigeon SofTouch T-Ester Bottle offers peace of mind to parents, allowing them to enjoy precious moments with their little ones while knowing that their baby's feeding needs are being met with a high-quality, research-backed product.
