The Ultimate Bottle Guide for Your Baby
Choosing the Right Bottle to Support Your Baby’s Feeding Journey
Introducing a bottle to your baby can feel like a big step, especially for those that are breastfeeding—and finding the right one is important to protect your feeding relationship and support your baby's comfort. Whether you are preparing for return to work, occasional bottle feeds, formula feeding, or supplementing, the right bottle can help support baby’s latch, flow control, and overall feeding experience.
Why the Bottle You Choose Matters
The bottle you pick is more than just a container for milk—it can directly impact how your baby feeds, digests, and stays connected to the breastfeeding experience.
A bottle that flows too fast can make feeding too easy, causing some babies to prefer the bottle over the breast (known as nipple confusion or flow preference). A poorly shaped nipple can lead to shallow latching, mouth fatigue, gas, or even swallowing air. These small things can quickly add up—impacting weight gain, comfort, and the overall breastfeeding relationship.
Choosing a bottle designed to closely mimic the breast, support a proper latch, and allow for paced bottle feeding helps protect:
Your milk supply (since baby won’t reduce nursing out of frustration or preference),
Your baby’s oral development and feeding skills,
Your baby's digestion and comfort, and
The ease of going back and forth between breast and bottle without stress.
In short: the right bottle supports both your breastfeeding goals and your baby’s feeding success.
When to Introduce a Bottle to a Breastfed Baby
Introducing a bottle at the right time can help your baby accept bottle feeding without causing disruption to breastfeeding. The general recommendation is to wait until breastfeeding is well-established—usually around 3 to 4 weeks—before introducing a bottle. This allows time for your milk supply to regulate and for your baby to develop strong, effective breastfeeding skills.
However, waiting too long (beyond 6–8 weeks) can make it more difficult for some babies to accept a bottle. Introducing a bottle once daily or every other day after 4 weeks can help your baby stay familiar with both breast and bottle.
Signs Baby May Be Ready for a Bottle:
Breastfeeding is going well with a strong latch and steady weight gain.
Baby is gaining weight appropriately.
Baby is showing signs of feeding readiness (rooting, sucking well).
If you plan to return to work, travel, or be away from your baby, introducing the bottle in advance gives time for practice and adjustment.
If you’re unsure about the best time for your baby, consult with a lactation professional to create a personalized plan.
What to Look for in a Bottle for Breastfed Babies
Slow Flow Nipples:
Breast milk naturally flows more slowly than formula bottles, and a slow-flow nipple helps mimic this pacing to avoid overwhelming your baby and to reduce the risk of bottle preference.Wide, Soft Nipple Base—With the Right Shape:
A wide base encourages a deep latch that’s similar to the breast, supporting oral development and making the transition between breast and bottle smoother. However, not all wide-based nipples are created equal.Some bottles have a wide base but a narrow nipple shape—this can actually encourage a shallow latch, which may interfere with breastfeeding by teaching baby a different mouth posture than they use at the breast. What we want instead is a gradual slope from the base of the nipple to the tip. This design encourages baby to open wide and take in more of the nipple, promoting a deep latch—just like we want at the breast.
Using a nipple with the proper slope and shape helps baby use the same oral skills with a bottle as they do at the breast, protecting both feeding technique and oral muscle development.
Some examples of bottles that have a wide base but a short or narrow nipple, which may encourage a shallow latch and therefore I do not recommend, include:
Comotomo
Tommee Tippee First Bottle
Philips Avent Natural
Anti-Colic Features:
Many bottles include vent systems to reduce swallowed air, which helps with gas, fussiness, and spit-up.Paced Feeding Compatible:
The bottle should allow you to use a paced bottle-feeding method, giving your baby the chance to control the flow—just like at the breast.

When (or If) to Change Nipple Size or Flow
One of the most common bottle-feeding questions parents ask is: “When should I move up in nipple size or flow?” The answer? It depends on your baby—and you may never need to change at all!
In fact, many breastfed babies stay on slowest-flow nipples for a very long time to help protect their latch, feeding skills, and prevent flow preference. For example: my own daughter used Dr. Brown’s Preemie Nipples until nearly a year old before transitioning directly to the Dr. Brown’s Transition nipple—and it worked beautifully for her needs. There’s no rule that says you must size up unless your baby clearly shows signs that they need it.
Signs that Your Baby May Be Ready for a Faster Flow:
Fussiness or frustration at the bottle
Biting down on the nipple (possibly out of impatience)
Pulling at or away from the bottle repeatedly
Feedings that are consistently lasting over 30 minutes with signs of fatigue
If you try moving up a nipple size and your baby handles it well—great! What works for your baby is what matters most. Just remember to continue paced bottle feeding with every nipple size, even as the flow increases. Bottle feeds should still take about 10–15 minutes to mimic the natural flow and rhythm of breastfeeding.
Important Note:
If your baby is thriving, feeding comfortably, and content with the current nipple size—you don’t ever have to change. There is no pressure to move up unless it improves feeding for your unique baby.
Helpful Tips for Bottle Feeding a Breastfed Baby
✔ Always use the slowest flow nipple available.
✔ Practice paced bottle feeding—hold baby upright and tip the bottle slowly to let baby control the flow.
✔ Offer skin-to-skin contact before and after bottle feeds to keep baby connected to the breastfeeding experience.
✔ Avoid switching bottles frequently. Give your baby time to adjust before deciding if a bottle is “rejected.”
Important Note: Every Baby Is Different
Some babies will take any bottle with ease. Others may have strong preferences. Start with one or two of these recommended brands and see what feels best for you and your baby.
Remember: a bottle is just a tool. You are what matters most in your baby’s feeding journey. If you’ve already found a bottle that works well for you and your baby—there is no reason to change! Every baby is unique, and what matters most is that feeding feels calm, comfortable, and effective for both of you. There is no “perfect” bottle for everyone—the best bottle is the one that supports your baby’s feeding and your peace of mind.
