Compare the Pigeon Preemie Silicone Nipple WS-2 with other slow flow options for premature babies. Learn when to choose WS-2 and when a faster flow might be needed.
Quick Answer
For most premature babies, the Pigeon Preemie Silicone Nipple WS-2 offers the gentlest, slowest flow to prevent choking and overfeeding. However, as your baby grows stronger, you may need to transition to a faster flow like WS-1.
Why Flow Rate Matters for Premature Babies
Premature babies have underdeveloped sucking reflexes and smaller mouths. A flow that is too fast can cause choking, coughing, or excessive air intake. A flow that is too slow may frustrate your baby and lead to poor feeding efficiency.
The Pigeon Preemie Silicone Nipple WS-2 is designed specifically for these delicate feeders. Its soft silicone material and extra-slow flow rate help your baby pace their feeding and reduce the risk of aspiration.
WS-2 vs. Other Preemie Flow Options
Pigeon offers two preemie nipple sizes: WS-2 and WS-1. WS-2 is the slowest flow, ideal for very small or weak premature babies. WS-1 is slightly faster and suits babies who have developed a bit more sucking strength.
The key difference is the flow rate. WS-2 delivers milk more slowly, giving your baby more control. WS-1 offers a moderate flow that still prevents overfeeding but allows for a more efficient feed.
There is no standard industry measurement for flow rates, so the best way to judge is by observing your baby's feeding cues. If your baby seems frustrated, falls asleep quickly, or takes a very long time to finish a bottle, WS-1 may be a better fit.
WS-2 vs WS-1: Tradeoffs at a Glance
- Flow Rate: WS-2: Extra slow. Best for very small or weak preemies. WS-1: Slow but slightly faster. Suitable as baby gains strength. Start with WS-2; consider WS-1 if feeding takes too long or baby seems frustrated.
- Baby's Sucking Strength: WS-2: Requires minimal effort. Ideal for babies with weak suck. WS-1: Requires a bit more effort. Better for babies who are growing stronger. Observe if your baby tires easily during feeding; if so, stick with WS-2.
- Feeding Duration: WS-2: Longer feeding sessions. WS-1: Shorter sessions. If your baby takes more than 30 minutes to finish a bottle, WS-1 may be a more efficient option.
