How to Introduce a Sippy Cup to a Breastfed Baby

Quick answer

Start offering a sippy cup around 6 months, once your baby can sit with support and shows interest in cups. Begin with a small amount of expressed breast milk or water at a low-stress time, not when your baby is starving. Offer the cup consistently for a few weeks and keep nursing as usual. If your baby refuses, pause and try again in a few days rather than forcing it.

Why breastfed babies often need a slower cup introduction

Breastfed babies are used to controlling the flow, pace, and comfort of nursing. A sippy cup introduces a different drinking action, so it can take several attempts before it clicks. That is normal. Your goal is familiarity, not replacing breastfeeds. Many parents find that offering the cup after a nap or between feeds works better than offering it when hunger is at its peak.

If your baby is under 6 months, speak with your pediatrician before offering water or a cup. The guidance here assumes your baby is around 6 months or older and has started or is ready to start solids.

Choosing a first cup that supports a breastfed baby

A soft, flexible opening can feel more familiar than a hard spout, and a small cup is easier for little hands to manage. The Cheers Happy Sippy Cup is made entirely of food-safe silicone with a simple three-piece design, which means fewer parts to lose and no hard plastic spout to adjust to. Its grow-with-me design includes optional handles that help babies who are still learning to grip.

You do not need a cupboard full of cups. Pick one and use it consistently so your baby builds a routine around it. If your baby is already using a silicone snack cup, the similar material and feel may make the transition easier. The Hello Snacks Happy Snacker is a two-piece silicone snack cup, not a drink cup, but it can help your baby get used to holding and using silicone feeding items.

How to set up a low-pressure first cup session

Timing matters more than technique. Choose a moment when your baby is calm, alert, and not overly hungry. Mid-morning or after a nap often works well. Put a small amount of liquid in the cup, just enough to cover the bottom, and offer it with a relaxed face. Let your baby hold it, mouth it, or tip it however they like. Spills are part of learning.

Do not swap out a full nursing session for the cup at first. Offer the cup alongside your normal routine so your baby does not feel pressured to choose. If your baby gets upset, end the attempt calmly and try again another day.

What to put in the cup and what to avoid

Expressed breast milk is often the easiest first fill because the taste is familiar. If your baby is 6 months or older, a small amount of water is also fine. Avoid juice and sugary drinks in a sippy cup, especially before age 1. Cow's milk is not recommended as a main drink before 12 months unless your pediatrician advises otherwise.

Keep portions small. A few ounces at a time reduces waste and keeps the cup from becoming a toy. If you are using expressed milk, offer it fresh or properly stored, and discard what is left after the session.

What to do when your baby refuses the cup

Refusal is common and rarely permanent. Try a different time of day, a different temperature for the milk, or a different position, such as sitting in a high chair versus on your lap. Sometimes letting your baby see you drink from an open cup or a similar cup sparks interest.

If your baby consistently turns away, arches their back, or cries when the cup appears, stop for a week. Continue nursing as usual and reintroduce the cup later. Forcing the cup can create a negative association that makes the next attempt harder. If your baby is older than 12 months and still refuses all cups, mention it at your next pediatrician visit.

Building the habit without rushing weaning

Offer the cup at the same times each day, such as with meals or after naps, so it becomes predictable. Let your baby practice holding the cup even if you need to help guide it. Over time, many breastfed babies begin taking more from the cup while still nursing. That is fine. The cup is an addition, not a replacement, unless you and your pediatrician decide otherwise.

Expect the process to take weeks, not days. Some babies take to a cup quickly; others need repeated exposure. Consistency and patience matter more than any single trick.

7 steps to introduce a sippy cup to a breastfed baby

1. 1. Check readiness signs: Wait until your baby is around 6 months, can sit with support, and shows curiosity about cups or food. If your baby was born prematurely, adjust for corrected age. Checkpoint: if your baby cannot sit with support yet, wait a few weeks and try again.
2. 2. Pick one cup and stick with it: Choose a small cup with a soft, flexible opening, such as the Cheers Happy Sippy Cup, and use only that cup for the first few weeks. Avoid rotating through different cups, which can slow familiarity. Checkpoint: if the cup has removable handles, start with them on for extra grip.
3. 3. Start with a familiar liquid: Offer a small amount of expressed breast milk or, for babies 6 months and older, water. Keep it to an ounce or two so the cup does not become overwhelming. Checkpoint: avoid juice and sugary drinks, and do not use cow's milk as a main drink before 12 months without your pediatrician's guidance.
4. 4. Choose a calm, low-pressure moment: Try after a nap or between feeds, not when your baby is very hungry. Sit your baby upright and offer the cup with a relaxed expression. Let them explore it. Checkpoint: if your baby cries or turns away, end the attempt and try again in a day or two.
5. 5. Keep nursing as usual: Do not replace a breastfeed with the cup at first. Offer the cup alongside your normal nursing routine so your baby does not feel forced to choose. Checkpoint: if you want to reduce nursing sessions, do it gradually and with your pediatrician's input.
6. 6. Repeat at the same times daily: Offer the cup with meals or after naps so it becomes predictable. Let your baby practice holding it, even if you need to help guide it to their mouth. Checkpoint: most babies need repeated exposure over several weeks before they drink well from a cup.
7. 7. Handle refusal without pressure: If your baby refuses for several days, pause for a week. Try a different temperature, position, or time of day. If refusal continues past 12 months, bring it up at a pediatrician visit. Checkpoint: forcing the cup can create a negative association, so back off and try later.
