When Should I Switch Baby Bottle Nipple Sizes?

Regardless of the specific brand you choose, most bottle manufacturers offer different nipple sizes or levels that correspond to specific age ranges. These levels are designed to accommodate your baby’s growth and developmental needs. For example, you may come across nipples designed for three or six-month-old infants.

While these age recommendations can serve as a helpful guideline, it’s important to remember that each baby has their own unique feeding style. Some babies may prefer nipples that are slightly smaller than their age-appropriate size. These babies might not consume large quantities of milk and are content to remain on Level 1 nipples until they are ready to start eating solid foods.

On the other hand, there are babies who are more enthusiastic eaters and may prefer larger bottle nipples that provide easier access to milk or formula. For these babies, transitioning to bigger nipple sizes earlier may be beneficial.

Ultimately, there is no definitive right or wrong time to change your baby’s nipple level. It’s crucial to observe your baby’s feeding behaviors and cues, as they will indicate when it might be appropriate to transition to a different nipple size. Trust your instincts as a parent and make adjustments based on your baby’s individual needs and comfort.

Signs to look out for

To ensure optimal feeding comfort for your baby, it’s important to be attentive to signs indicating whether the milk flow is too slow or too fast. If the flow appears too fast, switching to a smaller nipple size can help slow it down. Conversely, if the flow seems too slow, upgrading to a larger size can be beneficial.

Here are some indicators that it may be time to re-evaluate your baby’s nipple size:

Fussiness or irritability during feeding: If your baby becomes restless or cranky while eating, it could be a sign that the current nipple size is not providing an optimal flow rate.

Prolonged feeding sessions: If your baby takes an extended amount of time to finish a feeding, struggling to get enough milk, it might be an indication that the nipple size is too small for their needs.

Falling asleep while feeding: If your baby consistently drifts off to sleep during feeding sessions, it could indicate that the milk flow is too slow, making it difficult for them to consume an adequate amount.

As your baby grows, these signs usually suggest that a larger nipple size is necessary to provide easier access to milk. However, it’s equally important to watch out for signs of a too-fast flow, particularly in newborns. These signs include:

Swallowing hard




Refusing the bottle

Milk dribbling from your baby’s mouth

Dr. Brown’s Nipple Level Guide

We’ve covered when to change the bottle nipples, so now it’s time to talk about the best options. Here is a short guide for choosing the appropriate Dr. Brown nipple level.

0+ Months: Preemie Nipple

The Preemie Nipple is designed specifically for premature babies, providing them with a gentle and slower feeding experience. It is particularly beneficial for those transitioning from breastfeeding to bottle feeding, as the slower flow closely resembles the natural flow of breast milk.

It’s important to note that even the Preemie Nipple may not be small enough for some babies. In such cases, your pediatrician may recommend using Dr. Brown’s Ultra-Preemie Nipple, which provides the lowest flow rate available in Dr. Brown’s bottle nipple range.

0+ Months: Level 1 Nipple

The Level 1 nipple is the standard starter nipple that comes with most Dr. Brown’s bottles. It is commonly preferred by babies, particularly if they are feeding comfortably without any challenges. It serves as a suitable option for initial bottle feeding.

3+ Months: Level 2 Nipple

If you have noticed that your baby’s growth is causing the Level 1 nipple to flow too slowly for their appetite, it might be a suitable time to transition to a Level 2 nipple. The Level 2 nipple has a slightly larger opening compared to Level 1, allowing for a faster flow of milk.

In addition to accommodating your baby’s increased appetite, the Level 2 nipple is also a good choice when your baby starts accepting early solid foods or when you need to thicken their milk as recommended by your pediatrician. It provides a suitable flow rate for babies who are ready to progress beyond the early feeding stages.

6+ Months: Level 3 Nipple

If you observe that your baby is exerting extra effort or taking a considerable amount of time to extract milk from their Level 2 nipple, it may indicate that they are ready to transition to a Level 3 nipple in their Dr. Brown’s bottle.

Another indicator that your baby might be ready for a Level 3 nipple is if they are consuming more solid food or have reached a developmental milestone such as sitting up. Additionally, if your pediatrician suggests thicker milk or formula, a larger opening provided by the Level 3 nipple will ensure a steady flow.

By upgrading to the Level 3 nipple, you can accommodate your baby’s evolving feeding needs and help them extract milk more efficiently. As always, it’s beneficial to consult with your pediatrician to ensure the appropriate nipple level for your baby’s specific requirements.

9+ Months: Level 4 Nipple

As your baby progresses from Level 2 to Level 3, you may find that they still take a considerable amount of time to feed with the Level 3 nipple. In such cases, it could be an indication that a larger nipple size is needed.

By the age of nine months, most babies should be able to consume a substantial amount of milk or formula from the breast or bottle. If your baby is feeding consistently and without any difficulties at this stage, it may be appropriate to consider using the Level 4 nipple. The Level 4 nipple can be beneficial not only if you need to thicken your milk but also if your baby has started to transition to finger foods or can successfully drink from a sippy cup.

These developmental milestones indicate that your baby is ready for a faster flow and will be able to handle the increased flow rate without any issues. However, it’s essential to observe your baby’s feeding behavior and consult with your pediatrician to determine the appropriate nipple size for their specific needs.

9+ Months: Y-Cut Nipple

When your baby reaches around nine months of age and displays the growth signs mentioned earlier, another option to consider is the Y-Cut Nipple. The Y-Cut Nipple is larger than the Level 3 nipple and is specifically designed for thicker liquids such as thickened milk, formula, or cereal.

Using the Y-Cut Nipple can provide a suitable flow rate for these thicker fluids, accommodating your baby’s advancing dietary needs. It allows for a controlled flow that matches the consistency of the liquids, ensuring a comfortable and efficient feeding experience.

It’s important to note that the Y-Cut Nipple is typically recommended for older babies who have already developed the necessary oral motor skills to handle thicker textures. As always, consult with your pediatrician to determine if the Y-Cut Nipple is appropriate for your baby’s individual feeding requirements.
