Natural Instinct Teats
Lil’Kooee's Natural Instinct Teats have been designed to respect your baby’s biology, making feeding smoother, calmer and stress-free.
The narrow, naturally contoured shape supports a deep latch, simultaneously encouraging your baby’s natural suck-swallow-breathe rhythm. This promotes more controlled feeds, supporting healthy oral development and required nutritional intake.
Each teat is fitted with our custom Airshield® Valve, a unique air ventilation system that regulates airflow back into the bottle - not your baby's tummy - helping reduce colic, wind and reflux for happier, more comfortable feeds.
Available in multiple flow rates to match your baby's feeding stage and needs.
Here is a guide on our flow rates:
- ‘NB’ Flow (Newborns up to 5kg)
- ‘SS’ Flow (1-3 Months)
- ‘S’ Flow (3-6 Months)
- ‘M’ Flow (6-12 Months)
- ‘X’ Flow (12+ Months)

Visible Airshield® Valve Ventilation:
Parents can visually see the valve in action through a continuous formation or stream of air bubbles – clear proof the valve is working.
Supports a Deep, Natural Latch:
Narrow design encourages correct tongue placement and innate feeding techniques
True Slow Flow Options:
Allows babies to feed at their own pace for smoother transitions between breast and bottle.
Developmentally Supportive:
Encourages strong oral muscles essential for later chewing and speech.
Baby Safe Materials:
Made from 100% BPA and BPS free, food-grade silicone.
Due to the complexity of our Airshield® Valve shape and design we do not recommend microwave or UV sterilisation.
Recommended sterilisation methods:
1. Boiling
2. Electric Steam/Dry Steriliser
3. Dishwasher (Top Rack)

FAQs
Our Airshield® Valve has been specifically engineered using what's called a one-way release duck-billed valve. This valve works by breaking/releasing the vacuum created inside the bottle as bub drinks. This release of pressure establishing regulated airflow inside the bottle, venting air back into the bottle and away from being ingested by bub. This system is evident through a continuous stream of bubbles whilst bub is drinking.
By swallowing less air as they are feeding, this helps burping post-feed which in essense minimises the underlying factor of trapped air in their tummy - which is what exasperates colic, wind discomfort and reflux.
The narrow shape of our teats also allows for a tight seal, so there are no air gaps between the silicone and bubs lips. This stops air getting in through the sides of the mouth (a notorious issue with wide neck teats).
For those with a bub aged 0 - 3 months, our 'NB' and 'SS' have slower flow rates than all other narrow neck teats suitable for that age bracket. Our slower flow rates of 4.98mls/min (NB) and 8.69mls/min (SS), allow bub to calmly regulate their suck-swallow-breathe pattern which is a instinctive reflex that minimises gulping or fast swallowing - which is other common factor which exasperates colic, wind & reflux issues.
This is unfortunately a very common notion in the parenting space that was brought about due to the "Breast is Best" messaging forced-fed to parents since the introduction of wide-neck teats.
Here is the truth; silicone wide neck teats do not offer the same biological feeding mechanics of which a breast does. Granted, we do want a wide splay on a breast as this allows a baby's lips to engage with the areola, the area of skin around a nipple which communicates the let-down of breastmilk from the milk-glands. However, the key difference between a breast and a wide neck teat is that a breast nipple has a biological ability to extend deeper into a baby's mouth allowing for a deep latch and stimulation of lingual cupping with their tongue and therefore their natural sucking reflex. A wide-neck silicone nipple does not do this whatsoever. There is no areola on a silicone nipple so no communication is established between the milk glands, milk sinuses and the nipple for extension. This results in the common feeding issue of lip and lower jaw feeding, as a wide neck teat does not support a deep enough latch in a baby's mouth to trigger the sucking lingual cupping and the sucking reflex.
This biological knowledge and understanding extends to all maternity wards, where bubs who are beginning their breastfeeding journey are only offered a narrow neck teat if feeding support is required.
Overall, Lil'Kooee is focused on a baby's natural feeding instincts (hence the product name) around feeding. This is the reasoning behind our choice to use narrow neck teats.
A baby will not be required to pace-feed when using Lil'Kooee's bottles & teats. Thanks to our meticuously calibrated flow rates and Airshield® Valve technology, your bub's feeding experience using our bottles will be slow enough for them to regulate the feed themselves.
Please note, if you are using a different branded bottle currently and are having to pace-feed, it is most likely due to the fact the flow rate is too fast. Furthermore, the bottle positioning required to pace-feed also alters the mechanics of the venting system as most require the teat to be fully filled with milk.
Our Natural Instinct Teat flow rates are as follows:
1. 'NB' (Newborn up to approx. 5kg)
2. 'SS' (1 - 3 Months)
3. 'S' (3 - 6 Months)
4. 'M' (6-12 Months)
5. 'X' (12+ Months)
Ages are only a guide. Some babies will stay on a flow for longer than the specified age or move up faster than expected. As a rule of thumb, a feed under 12 weeks should take 30-40 minutes, similar to breastfeeding. After 12 weeks a feed should start to pick up speed and take approx. 20 mins to complete. If they start to take longer or reduce volume, then it's time to try the next flow rate.

Yes! We had these teats tested by Infant Feeding Labs USA, to ensure our flow rates were sitting in the genuine slow flow range. Teat flow rates are a unregulated factor to teat manufacturing, so bottle and/or teats claiming to be suitable for newborns can have a flow rate anywhere from 5ml to 45mls per minute.
For reference, our 'NB' teats are 4.98mls/minute and our 'SS' teats are 8.69 mls/minute.
