The Thick feed nipple (with the letter Y on the nipple) is recommended for babies of 6+ months old. This sturdier nipple has a Y-shaped slot for thicker feeds to flow through.
When to change flow rate
If you are breastfeeding, we suggest staying with the Natural First Flow nipple because it is designed to match the flow rate of the mother.
If your child becomes frustrated at meal times. You may see them suckling hard then pulling away crying, suckling hard again or your baby is taking longer than 20 to 30 minutes to finish a bottle; this may be an indication that the flow is too slow. If this the case change to a nipple with a higher flow rate.
If your baby has to let go of the nipple, is spilling milk, is getting too much milk too swallow or milk is dripping between the lips and the nipple, the flow rate might be too fast, change to a nipple with a lower flow rate.
You can also use the Natural nipples with screw ring in combination with the Classic/Classic+ Feeding Bottles.
