Compare Lansinoh NaturalWave Slow and Medium Flow Teats to find the right flow for your baby's age and feeding needs.

Quick answer

Choose the Slow Flow teat for newborns and younger breastfed babies who need a gentle, controlled milk flow. Switch to the Medium Flow teat when your baby is older and wants milk faster, typically around 3-6 months.

Why flow rate matters for feeding

A teat's flow rate controls how fast milk comes out. Too fast and a baby may gag or refuse the bottle; too slow and they may get frustrated and give up. Matching the flow to your baby's age and feeding strength helps them feed comfortably and avoid swallowing air.

The trade-off: slow vs medium

The Slow Flow teat is ideal for newborns and younger babies because it mimics the natural milk release from the breast, reducing the chance of overfeeding. The Medium Flow teat offers a faster milk delivery that suits older babies who have developed stronger sucking skills and need more milk per feed.

How to choose between Slow and Medium Flow

  • Slow Flow Teat (Newborn+): Best for newborns and younger babies (0-3 months) who need a gentle, controlled flow. Helps prevent overfeeding and supports breastfeeding patterns. Start with Slow Flow and observe your baby's cues. If they seem frustrated or take a long time to finish a feed, it may be time to move up.
  • Medium Flow Teat (3-6 months+): Suitable for older babies who have developed stronger sucking skills and want milk faster. Offers a faster flow while still reducing nipple confusion. Switch to Medium Flow when your baby shows signs of impatience with the Slow Flow, such as fussing or taking longer than 20 minutes per feed.
  • When to switch: Watch for signs like your baby getting frustrated, taking longer to finish a bottle, or not seeming satisfied after a feed. These are clues they may need a faster flow. Always monitor your baby's feeding cues and consult your healthcare provider if you have concerns about feeding pace.
