Quick answer
Choose a slow flow nipple for newborns and younger infants, and a medium or fast flow as your baby grows. The Lansinoh NaturalWave Nipples 4-Count pack includes one of each flow rate (Slow, Medium, Fast, and Extra Fast) so you can match the pace to your baby's feeding needs.
Why flow rate matters for breastfed babies
Breastfed babies are used to controlling the milk flow themselves. A nipple that releases milk too quickly can overwhelm them, while one that is too slow may frustrate a hungry older baby. Matching the flow rate to your baby's age and feeding ability helps maintain a natural feeding rhythm and reduces the risk of nipple confusion.
The Lansinoh NaturalWave Nipple is designed to mimic the natural sucking action at the breast. The nipple shape and flex allow your baby to use the same tongue and jaw movements as when nursing, supporting a smooth transition between breast and bottle.
Compatibility with Lansinoh bottles and other brands
These nipples are designed to fit all Lansinoh bottles, including the standard 5 oz and 11 oz sizes. They also fit most wide-neck bottles from other brands, but always test the seal before first use. If the nipple feels loose or leaks, it may not be fully compatible.
The 4-count pack gives you one of each flow rate, so you can try different ones without buying separate packages. This is especially helpful if you are unsure which flow your baby needs.
Decision rules for choosing a flow rate
- Newborn (0-3 months): Use the Slow flow nipple. It releases milk slowly, matching the pace of early breastfeeding and preventing gagging or overfeeding.
- Infant (3-6 months): Switch to the Medium flow nipple. Your baby's sucking strength has increased, and they will get milk more efficiently without frustration. If your baby seems impatient or pulls away, try the Fast flow next.
- Older baby (6+ months): Use the Fast or Extra Fast flow nipple. Older babies drink more and faster. The Extra Fast flow is best for very hungry or impatient feeders. Watch for signs of gulping or milk leaking from the mouth — that means the flow may be too fast.
