Polyamide (PA) is a high-performance thermoplastic nylon that is lightweight, durable, and has glass-like clarity. Unlike other bottle materials, PA withstands high temperatures, making it safe for most sterilisation methods. It also doesn’t absorb odors or colors and is 100% BPA, BPS, and BPF-free.

After extensive research, we chose PA because it eliminates common concerns parents have with other materials like PP, PPSU, glass, and silicone. Combined with our Natural Instinct Teat featuring the Airshield™ valve, Lil’Kooee bottles provide a safe, hygienic, and superior feeding experience for babies and parents alike.

PP (polypropylene) is a plastic material that has a naturally cloudy transparency and is the most common choice for many other brands with baby bottles due to it's cost effectiveness. However, some PP plastics have been scrutinised due to additional dyes and colorants being added to try and achieve a less "milky" or opaque final appearance. Similarly, while PPSU is a premium, safe and high performing material available on the market, many parents are reluctant because of it’s yellow, “honey toned” appearance, as it makes the contents difficult to see and its cleanliness hard to determine. Therefore, we have opted to use PA as the overall better, more premium medical grade material, as it offers glass-life clarity, exceptional durability and is guaranteed BPA/BPS/BPF free.

We strongly believe that our narrow neck Natural Instinct Bottles should be the feeding bottle all parents should be choosing for the baby. Combined with our Natural Instinct Teat, with its integrated Airshield™ air release valve, our narrow neck bottle combination works in sync with a baby’s natural rooting reflex. This reflex is triggered by the peristaltic wave of a baby’s tongue and their palate working in unison whilst a baby is sucking. Our Natural Instinct Teat sits instinctively in a baby’s mouth, stimulating their biological and rhythmic sucking motion to feed. This is in comparison to a wide neck bottle, which forces the use of their lips and lower jaw to overwork to extract the milk. This is typically apparent by a sucking blister commonly seen on a baby’s top lip.

It should be noted that all plastics including PA are not as heat-resistant as glass. Therefore, we DO NOT recommend using microwave or UV sterilisation for frequent bottle sterilising. This is due to their highly volatile temperatures degrading the material much faster than other methods. Instead, we recommend boiling, countertop steam/dry sterilizers or hand washing/dishwasher (top-rack) for frequent/everyday bottle sterilising. These sterilisation methods have been thoroughly tested with our Natural Instinct Bottles for which they passed with flying colours!

For our Natural Instinct Bottles, we recommend replacing them every 12 months for a single bottle which is sterilised and used once a day. However, if you find yourself using and sterilising a single bottle more than once a day, we recommend replacing it more frequently for optimal usage. Also, whilst our bottles are made from a highly durable, scratch free material, damage can still occur after repeated use, it is recommended to discard the bottle and replace after first signs of wear or damage.

Many narrow-neck bottles on the market have issues with air regulation, causing teat collapse, leaks, and inconsistent milk flow. Lil’Kooee’s Natural Instinct Teat solves these problems with its unique Airshield™ valve, which regulates airflow to prevent gas, colic, and spit-up.

Unlike other teats, our design ensures a consistent flow rate without requiring parents to adjust the cap. Plus, our bottle lids feature a built-in spur to prevent leaks when stored or shaken. A comfortable, frustration-free feeding experience for both baby and parent!

Every baby is unique, and their feeding needs can change as they grow. To make finding the perfect flow rate easy, Lil’Kooee offers Natural Instinct Teat Trial Packs.

• Stage 1 Trial Pack: Includes NB, SS, and S teats (suitable for newborns to 3+ months).
• Stage 2 Trial Pack: Includes S, M, and X teats (suitable for 3+ months to 12+ months).

These packs allow you to test different flow rates without the guesswork or extra expense—helping you find the best option for your baby’s comfort and feeding pace.

Both our bottle sizes come with teats! Our 120ml Natural Instinct Bottle comes with our ‘NB’ (Newborn) teat suitable for newborns up to 5kg. Our 240ml comes with our ‘S’ teat which is most suitable for little ones 3+ months.

For our Natural Instinct Teats, we recommend replacing them every 12 weeks for a teat that is sterilised and used once a day. However, if you find your little one likes a more intensive feed, then we recommend replacing teats more frequently for optimal usage. Also, examine your teats before use, if you notice any signs of wear and tear, discolouration or cracks, discard the teat and purchased a new set. You can also find this same reminder on the side of our teat packaging!

With there being a huge societal push on independent feeding, there has been a surge in wide front and deep based spoons which are all designed in the hope a baby will be able to at least fit some of it in their mouth. It has come apparent to parents that these types of spoons don’t suit little ones, who are ready for solids, prior to 6 months old, or even those that prefer soft food over baby led weaning. Lil’Kooee recommends that all babies should experience feeding with a spoon so they are guaranteed a full tummy, yet very few options are on the market. The only other similar option uses PP plastic in their design.

Our Founder Susie has specifically designed our Lil’Kooee silicon Weaning Spoon around this issue, so bubs can have a successful and enjoyable feeding experience. The flat, thin tip is perfect to get past sensitive little gums and lips, and the width of the spoon means they don’t have to overstretch their mouth. Additionally, the deeper base at the back of the spoon head means it will complement self-feeding when they are developmentally ready to do so!

Most babies are ready to commence first solids between 4-6 months. Our spoons are designed to ensure a positive and memorable solids experience. When they are developmentally ready the spoon will fit into a little one’s hand and has a short enough handle to encourage self-feeding.

The main concern for parents who choose a narrow neck bottle is the mess that is created when adding formula or other contents through such a narrow opening. Especially when working one handed or when in a rush!

Lil’Kooee has created a product when resolves this issue, with our very own “Formula Funnel”. Our funnel sits snug in the neck of both our Natural Instinct Bottles, allowing for the same opening size you would have with a wide neck bottle.

Trying to clean hard-to-reach areas, specifically the bottom grooves of a narrow neck bottle, can be a really frustrating, tedious task. Especially if there is formula residue stuck down there! To make this task much easier and much quicker, we recommend using our Bottle and Teat Cleaning Set.

Included in the set are our Bottle Cleaning Brush and Teat Cleaning Brush. Our bottle cleaning brush is designed to not only fit perfectly in our Natural Instinct Bottles, but also allows for a quick, hygienic clean thank to its ergonomic, 360° rotating handle. Our Teat Cleaning Brush has a rigid, silicon ridges covering all sides of the tip which also allows for a quick, hygienic cleaning process.

The best types of feeding bowls are typically lightweight, non-slip and have high sides for easy scooping. Our “Grip ‘n’ Go Bowl” has all these attributes as well as a strong, suction base which holds it down to any smooth surface. No more food flying across the kitchen or living room! Our “Grip ‘n’ Go Bowl” is perfect for both at home and on-the-go, making snack time easier for bub and mess free meal times for parents! The tight fitting silicon lid makes left overs a breeze as the lid keeps food fresh in the fridge or back in the baby bag.

Yes, the formula dispenser has 4 raised sectioned sides that sit snug up against the inside of the lid so when you turn in upside down to tap into the bottle the remaining portions will stay within the sections.
