The ages shown on our packs are just an indication as every baby has their own drinking rhythm and the best teat flow will depend on how they drink.
Try a higher flow if your baby seems frustrated during feeds, falls asleep during feeds, or plays with the teat instead of drinking. Try a lower flow if your baby has milk leaking from their mouth or is gulping the milk down.
We have moved to a pace-based flow navigation system. Start with the teat that comes with the bottle. Slow down enthusiastic drinkers with our lower flows, or help steady drinkers with our higher flows.
You can see the before and after in this table.
