Parents often assume age on the box is a strict rule, but teat flow depends on your baby's individual sucking strength and feeding pace.
Flow 1 (0m+ Newborn): Recommended from birth until baby consistently takes more than 20 minutes per feed or collapses the teat from vigorous sucking.
Flow 2 (1m+ Slow) & Flow 3 (3m+ Medium): Transition when you notice baby pulling away frustrated, falling asleep mid-feed from fatigue, or kicking during feeds.
If baby coughs, milk drips from mouth corners, or feeds finish in under 7 minutes, the flow is too fast. Step back down one level to protect comfortable digestion.
