To achieve your breastfeeding goals, you may choose to pump and store your breast milk so that it is always available when your baby needs it, even when you are away or your partner wants to feed your little one. It is recommended that you spend six to eight weeks establishing a regular breastfeeding pattern before introducing a bottle. It is also advisable to discuss all options with your midwife or lactation consultant, as they will be best placed to advise you on when the best time to introduce a bottle is, depending on your individual situation. It's important to feel confident that your baby will return to the breast when they come back, so choosing the right bottle to avoid confusion with the teat is crucial. The Lansinoh mOmma bottle with NaturalWave teat has been specially designed so that your little one can enjoy your expressed breast milk, even when you are separated. Based on more than 50 years of research, the NaturalWave teat encourages your baby's instinctive sucking movement for natural oral development, helping you to switch easily between breast and bottle and maintain your established breastfeeding patterns. Extensive research has shown that a baby's sucking style is very different from that of an adult and involves three important steps: the initial latch-on, the peristaltic tongue movement (where your baby's tongue moves in a wave-like motion) and the swallow. It is very important that a baby can perform the peristaltic tongue movement as it promotes natural oral and jaw development. The NaturalWave teat from Lansinoh is clinically proven to support this natural feeding pattern. Size S
