Lil'Kooee's Natural Instinct Teats are designed to respect your baby's biology - making feeding smoother, calmer and stress-free. The narrow, naturally contoured shape supports a deep latch and your baby's natural suck-swallow-breathe rhythm, promoting healthy oral development and controlled feeds. Each teat features our custom, Airshield® Valve, which regulates airflow back into the bottle - not your baby's tummy - significantly reducing colic, wind & reflux.

What Parents Are Saying...

Game Changer!

I am So excited I found these teats!!!! We are mix feeding our baby boy and he has taken to these bottle teats so well without any issues moving between bottle and breast. I was so worried about him getting gassy/fussy with a bottle but we haven't had any issues! we started with the 'NB' teats and have used the SS... now time for the S! I'm so happy we found a teat that really does what it says it will do <3 Thank you Lil'Kooee

5 Stars!

Honestly the Lil'Kooee teats are brilliant, I couldn't speak more highly of them!! My 3 month old baby girl has a very high palate and an extremely strong sucking reflex. She also suffered from symptoms of colic and silent reflux, struggled with trapped gas after bottle feeding EBM. Until we found Susie and these amazing bottles and teats!!! No more tummy troubles after bottles, the teats are strong and stable (does not collapse). The special design of the teat and narrow neck bottle enables a full and secure latch (great for colicky gals) Please do yourself and your babe a favour and switch to Lil'Kooee, I promise you won't regret it

No More Tummy Troubles

I love these teats for my twins, the internal valve means both babies can drink at their own pace while all the air goes back into the bottle and not their tummies. Both of them now get their burps up so quickly and easily which means a lot when you're trying to juggle two babies. I had issues with my pidgeon teats causing a vacuum and constantly having to readjust the lid but that isn't an issue at all anymore with these teats, they've taken all the frustration of bottle feeding two babes away. Thank you!!!!

Best Teats Ever

I have tried several different brands of bottles and teats and I can truthfully say these are by far the best ones on the market. The quality is definitely noticeable and the valve is genius! I love that I can see the air bubbles! Burping is so much easier and spit up so much less!

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 a common question, and it stems from the "Breast is Best" messaging that has shaped parenting advice since wide-neck teats became popular. Here's what the science actually tells us.

The key difference between a breast and a wide-neck teat

A real breast nipple can extend deep into a baby's mouth, which does two important things:

  • Creates a deep latch
  • Stimulates lingual cupping - the natural tongue movement that triggers a baby's sucking reflex

A wide-neck silicone teat cannot replicate this. It also lacks an areola, which on a real breast acts as a signal between the skin, milk glands, and nipple to coordinate milk flow.

Without these mechanics, babies tend to compensate by feeding from their lips and lower jaw - a shallow latch that can cause feeding difficulties.

What about the wide splay of a breast?

Yes, a wide lip splay is important when breastfeeding - it helps a baby engage with the areola. But that's not what wide-neck teats are designed to replicate. The shape looks similar, but the function is entirely different.

What hospitals do

Maternity wards recognise this distinction. When newborns need feeding support while establishing breastfeeding, they are offered narrow neck teats - not wide ones.

Our approach

Lil'Kooee is built around supporting a baby's natural feeding instincts. Narrow neck teats more closely support the deep latch and sucking mechanics a baby is biologically designed to use - which is exactly why we chose them.

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.
