Natural Instinct Teat

Can't See Air Bubbles?

Sometimes the valve may not open properly due to formula residue getting stuck inside or very rarely they can sometimes reseal after sterilisation. If you are finding there are no bubbles visible during a feed, the valve may need to be manually opened. If you use your two thumbs, place them on either side of the valve, and gently squeeze the valve, it will open - please refer to the photo as an example of this.
Please note, every online order that includes Natural Instinct Teats will also have a small white stick with a blunt tip, which can also be used to gentle spread the valve flaps open instead. Please refer to second photo as an example of this.
If neither of these methods work for you, please contact us and we will help you resolve the issue.
