Introducing a Bottle to Your Breastfed Baby—When, Why, and How to Do It Gently
So you’re breastfeeding and thinking about introducing a bottle—whether it’s to prep for going back to work, to give yourself a break, or simply because you want to have the option. But figuring out when to do it, how to do it, and what bottle to use can feel like a bit of a guessing game.
Let’s take the stress out of it. Here’s everything you need to know about introducing a bottle in a way that supports your breastfeeding journey—and your peace of mind.
Do You Have to Introduce a Bottle?
If you’re not planning to be away from your baby in the first 6 months—and breastfeeding is going well—you absolutely don’t need to. There are other ways to feed your baby if you ever need to step away, like cup feeding, syringe feeding, or even having a trusted lactating friend or family member nurse your baby.
But sometimes, there are medical reasons to introduce a bottle earlier. Maybe baby can’t latch, is struggling to gain weight, or you’re working through low supply and supplementing. In those cases, bottle feeding can be part of a supportive plan—but remember, every bottle of milk given should be matched with a pumping or hand expression session to protect your supply.
When Is the Best Time to Introduce a Bottle?
The sweet spot is usually between 2–4 weeks—once breastfeeding is well established but before baby becomes too set in their ways. This window allows time for you and baby to find your rhythm, while still giving baby a chance to learn a new skill without much resistance.
That said, if you’re not planning to use bottles, you can skip this altogether. But if you are—starting early (but not too early) is key to helping your baby feel comfortable with both breast and bottle.
And remember: if your partner wants to help with feedings at night, you’ll still need to wake up and pump to keep your supply steady. But there are plenty of other beautiful ways to bond—like babywearing, skin-to-skin, and diaper changes with silly songs. The milk isn’t the bond—it’s the presence. 💛
How to Offer a Bottle Without Derailing Breastfeeding
There’s no one “right” way to introduce a bottle, but there are a few strategies that can make the experience smoother—for both of you.
Offering a bottle before nursing can be helpful if baby is more motivated by hunger, but it can also lead to frustration if they’re too hungry to try something new. The upside? Baby can still finish the feed at the breast (aka their favorite place), which creates a positive association.
Offering after nursing is a gentler option and supports your supply. Baby gets the benefit of practicing at the breast first, and since they’re already full, they might be more relaxed and curious about trying a bottle.
Offering a bottle as a “snack” works great if breastfeeding is going well and you’re just working on bottle feeding as a skill. You don’t need to replace a full feed—just offer a little once a day, whenever it feels natural. Some moms even use the milk they collect with a passive milk catcher—no extra pumping needed!
Bottle Feeding Positions That Help Baby Feel Safe & Supported
Just like breastfeeding, bottle feeding should feel cozy and connected. Try holding baby upright on your chest, in a side-lying position across your lap, or cradled with their knees slightly raised. Skin-to-skin can help babies stay calm and engaged, and don’t forget to switch sides from time to time—that’s good for oral development, too.
Which Bottle Is Best?
There’s no perfect bottle, but we do have a few favorites. For babies under 4 weeks, Dr. Brown’s bottles with the preemie or newborn (T) nipple are a great place to start. They offer a nice slow flow and are widely available.
Once breastfeeding is going well (usually after the 4-week mark), we also love:

LactationHub GentleFlow+ bottles
The shape of the bottle matters, too. A gradual slope (not a super wide, boob-shaped nipple) tends to support better oral function. A good latch on a bottle looks a lot like a good latch at the breast. If baby is clicking, leaking milk, or seems frustrated while feeding, something may be off with the nipple shape or flow.
Paced bottle feeding (check out our blog on that here!) can also help babies stay regulated and mimic the flow of breastfeeding.
When to Ask for Help
If your baby is refusing bottles, choking or coughing during feeds, or you’re not sure how to introduce a bottle in a way that supports your supply—don’t wait to reach out. These are all things a lactation consultant can walk you through, either virtually or in person.
