Frequently Asked Questions
Which flow rate is best for my baby? +-
Every baby is different and will require different flow rates at their own pace and stage. Our suggested age & flow rates are the following:
Slow Flow: 0+ months
Medium Flow: 0+ months or 1+ months
Fast Flow: 6+ months
You can find our suggested flow rates on each NUK® bottle packaging. Remember, everything is dependent on your baby's development.
How can I help prevent colic when bottle feeding? +-
Make sure that you are choosing a bottle with an anti-colic feature. All NUK bottles feature an innovative Anti-Colic vent system which helps to reduce the risk of infant colic. The valve allows air into the bottle during feeding which prevents an air vacuum and allows baby to feed continuously without swallowing air. In addition, always ensure your baby has a good seal around the nipple to prevent baby from swallowing air from the sides of their mouth.
What is BPA? +-
BPA or Bisphenol A is a raw material used in the manufacture of the synthetic material, polycarbonate (PC). PC is used in various everday items such as plastic bags, phones, CD's and adhesives. Numerous studies have been conducted to identify the dangers of BPA intake with inconsistent and inconclusive results. However, as a safety precaution, all NUK bottles, pacifiers, cups and tableware are BPA-free.
Which NUK® bottles and nipples are interchangeable? +-
Bottle nipples and replacement nipples are interchangeable within NUK product lines: NUK® Simply Natural™, NUK® Perfect Fit™ & Gerber® First Essentials™. NUK Simply Natural nipples are interchangeable among all Simply Natural tritan 5oz or 9oz bottles and 4oz or 9oz glass bottles. NUK Perfect Fit nipples are interchangeable among 5oz and 10oz Perfect Fit bottles, 5oz and 10oz Perfect Fit Learners and NUK soft spout and hard spout Active Cups. Gerber First Essentials nipples are interchangeable among 5oz and 9oz First Essentials bottles.
What is the difference between latex and silicone nipples? +-
Both nipple materials have their own special characteristics. NUK® silicone nipples are made of a high-quality polymer synthetic material. This transparent silicone is heat and age-resistant and very easy to clean. Latex is a natural rubber product that is flexible, bite and tear-resistant. Since latex is a natural material, edible fats and exposure to direct sunlight may age it somewhat quicker than silicone. Which material you choose depends on your individual wishes or preferences and those of your baby too. Of course, you can always switch from one type to the other.
Can I use the NUK® latex nipples with any NUK bottle? +-
No, NUK Latex nipples fit most ready to feed, single-serve formula bottles.
Can I use the Gerber® First Essentials™ latex nipples with any NUK® bottle?+-
No, Gerber First Essentials latex nipples can only be used on Gerber First Essentials 5oz or 9oz bottles.
Do you sell any bottles that are glass?+-
Yes, NUK® Simply Natural™ glass bottles are available for purchase.
Are NUK® bottles dishwasher-safe?+-
NUK and First Essentials™ Bottles are dishwasher-safe, top rack only. This includes all parts of the bottle: bases, nipples, rings and caps.
Are your bottles and products recyclable?+-
Most NUK® bottles and products are recyclable and are marked with the recycle symbol. Please note that Tritan bottles are not recyclable.
When should I change my child’s pacifier size and why?+-
As baby grows, so does the size of their palate. Therefore, they require a larger pacifier baglet for proper soothing. NUK® offers pacifier sizes at every stage of development starting from Newborn to 36 months. We suggest you change your baby's pacifier size at 2 or 3, 6 and 18 months of age. Our suggested ages & sizes are the following:
Newborn: 0-2 months
100% Silicone: 0-3 months
Size 1: 0-6 months
Size 2: 6-18 months
Size 3: 18-36 months
You can also find our ages & sizes on each NUK pacifier packaging. For hygiene and safety reasons, we recommend replacing pacifiers after 2 months of use.
Round soothers vs asymmetrically-shaped soothers: why is asymmetrical better?+-
The original NUK® orthodontic nipple is asymmetrical to promote healthy oral development. Its natural shape mimics mom’s nipple while breastfeeding and the scoop bottom nipple allows for maximum tongue movement. NUK pacifiers also promote the natural development of baby's teeth and jaw through integrated channels on the orthodontic nipple that reduce jaw and palate pressure.
What is better – puller or button?+-
That's totally up to you and your baby's preference!
What do I need to know about pacifier hygiene?+-
Before your baby uses a new NUK® pacifier for the first time, sanitize the pacifier by boiling it in water for 5 minutes. For daily cleaning, wash with hot water and mild detergent, then rinse clean. NUK pacifiers are dishwasher-safe, top rack only. Water may get inside the nipple during cleaning, and can be removed by squeezing the nipple. For hygiene and safety, replace pacifiers after 2 months of use.
How often should I replace my pacifier?+-
For hygiene and safety reasons, we recommend replacing pacifiers after 2 months or if any tear or crack appears.
Can I combine bottle and breastfeeding?+-
Yes! Through our NUK® Simply Natural™ line we make it as easy as possible for baby to transition back and forth between breastfeeding and bottle feeding while maintaining the special bond between mom and baby. The NUK Simply Natural bottles are designed to be the closest to mom's breast featuring a super-soft silicone nipple that feels, flows, and moves just like mom’s for a comfortable latch. The nipple is shaped just like mom's nursing nipple and has multiple nipple holes just like mom for more a comfortable and natural feed. Click here to learn more about NUK Simply Natural.

What is the best way to care for my breast pump?+-

What are the differences in sippy cups and learner cups?+-
Learner or trainer cups are designed to help make the transition from bottle to independent drinking easier. NUK® learner cups have easy-grip, anti-slip handles that are easy for baby to hold and can be removed to grow with baby. The soft silicone spout is gentle on baby's gums and includes an air vent that helps reduce swallowing of air. NUK learner cups are recommender for babies 6 months and older. Once your baby is ready to hold a cup without handles, they may be ready to move on to active cups! While NUK active cups maintain the shape of a large learner cup, it gives baby the opportunity to drink independently without handles. NUK active cups also come with a clip for on-the-go carrying in soft spout and hard spout versions. Once baby gets comfortable with holding their own cup, they may be ready to move on to sippy cups. NUK offers sippy cups in a variety of spout types such as 360, straw and hard spout. Recommended ages vary from 6 months to 12 months. Explore different spout types with your baby to discover what they like best!
What are the benefits of hard spout vs. soft spout?+-
Hard spout and soft spout cups each have their own benefits depending on baby's stage of development. Soft spout cups are designed to make the transition from bottle to cup easier since the silicone spout is gentle on baby's gums. Once teeth emerge, a bite-resistant hard spout cup with a similar shape to soft spout helps continue with transition to independent drinking.
