LuvLap Essential Feeding Bottles are ergonomically designed to be easily held while feeding the baby. All LuvLap bottles are 100% BPA free and fully sterilizable. The teats are 100% Liquid Silicone and have an anti-colic valve that vents air into the bottle, preventing any air from entering the baby’s tummy. The teat has spiral grooves at the tip, which encourage peristaltic suckling, and help the baby get a comfortable latch. The grooved teats and superior silicone quality ensure no nipple collapse, helping in an uninterrupted feed. With the LuvLap Essential Feeding Bottles at your side, your baby’s feed will always be a comfortable one
