How Many Ounces Should I Be Pumping by Baby Age?

Pumping breast milk can be a bit overwhelming, especially when you’re trying to figure out how much your baby needs as they grow. It’s important to know the right amount to pump at each stage of your baby’s development to ensure they’re getting enough nutrition. In this article, we’ll break down how many ounces you should aim to pump by your baby’s age and share some helpful tips for keeping up your milk supply along the way.
What Influences Breast Milk Supply?
Breastfeeding is a miracle process, but many have questions as to why the milk supply could be different from one mother to the other. Knowing what controls the way your body manufactures milk may be an enabling factor. Here are some of the key factors affecting how much breast milk you will be able to produce.
1. How Often You Feed Your Baby
The more frequently you breastfeed or pump, the more stimulation your body gets to make milk. Regular feedings help maintain and increase your supply by continuously telling your body to keep producing.
2. Mom’s Health and Diet
The overall health of the mother, including good nutrition and proper hydration, is considered important in the production of milk. Stress, exhaustion, and other forms of illness negatively affect milk production.
3. Hormones at Work
The key hormones involved in the production and release of breast milk are prolactin and oxytocin. Thyroid conditions and complications during and after childbirth can alter the balance of these hormones and thus impact milk supply.
4. Breast Size and Milk Storage
Some women naturally have a larger storage capacity in their breasts, allowing them to produce and hold more milk between feedings. This is a physical trait and varies among individuals.
5. Getting a Good Latch and Fully Draining Milk
A good latch with a complete expression of milk at each feeding or pumping is very important. If the breasts are not emptied completely, the body receives a signal that it needs to produce less milk over time.
Every mother has a different breastfeeding experience, and understanding the many factors that affect milk supply can help you through those tough times. Trust your body and seek advice to keep your breastfeeding experience healthy and rewarding.
Factors Affecting Breast Milk Demand
Just as milk supply can differ among mothers, so too can the demand for breast milk fluctuate depending on several factors related to your baby. Recognizing these can help you better adapt to your baby’s nutritional needs and ensure a smooth feeding experience for both of you.
1. When Your Baby Goes Through Growth Spurts
During growth spurts, babies tend to feed more often, increasing the demand for breast milk. These periods require your body to adapt to higher milk production.
2. Age Affects Your Baby’s Eating Habits
As babies grow and develop, their nutritional needs change, which can influence how often they feed. Newborns typically feed more frequently than older infants.
3. Starting Solid Foods
When solid foods are introduced, usually around six months, the demand for breast milk may gradually decrease as solids begin to complement the baby’s diet.
4. Your Baby’s Health and Growth
A baby’s health conditions or developmental milestones, such as teething or illnesses, can temporarily alter feeding patterns and affect milk demand.
5. Using Bottles and Pacifiers
Frequent use of bottles or pacifiers might reduce the frequency of breastfeeding sessions, potentially lowering the demand for breast milk if not managed appropriately.
Adjusting to changes in your baby’s milk demand can feel like a balancing act, but it’s all part of the evolving nature of parenting. By staying attuned to your baby’s cues and being flexible with your approach, you can support their growth and development while maintaining a positive breastfeeding relationship. Embrace each stage of this journey with confidence and curiosity.

Newborn Stage (0-1 Month)
During the first days after birth, your body produces colostrum, a nutrient-rich, thick yellowish fluid that meets the newborn’s nutritional needs. Colostrum is packed with antibodies and acts as a natural immune booster for your baby. After a few days, your milk transitions to mature milk, which becomes thicker and more plentiful. During the first weeks after giving birth, pumping sessions yield only about 1-2 ounces per session; this is normal since your baby’s stomach is small.
To maximize your milk supply in this early period, consider frequent pumping-ideally every two to three hours or whenever your baby is feeding. This can stimulate your milk production by mimicking the demands of the baby’s mouth. Besides that, skin-to-skin contact with your baby may be used to help with lactation through the stimulation of hormonal releases such as prolactin and oxytocin, which are necessary for milk production. Hydration, proper nutrition, and rest will also support successful lactation.
Infant Stage (1-3 Months)
As the baby grows in the 1-3 month stage, his nutritional needs raise the demand for more milk. At this age, babies consume more milk in each feeding as their stomachs grow bigger and they rapidly develop in growth. During this period, mothers often notice an increase in the amount of milk needed; this is generally around 2-4 ounces per pumping session.
Try to pump every 2-3 hours during the day, using the same pattern your baby follows for his feedings. This schedule helps your body get a good signal for how much milk it needs to make. Also, be sure to use a good quality breast pumpyour milk supply. Also, consider incorporating some relaxation techniques, such as deep breathing or gentle massages, to reduce stress, which can negatively impact milk flow.
Baby Stage (3-6 Months)
During the 3-6 month stage, your baby’s feeding patterns begin to regulate, and they get into a routine. This is often accompanied by longer stretches between feedings and possibly more sleep at night. You may find that both feeding and pumping sessions become more predictable.
Typical pumping at this age runs between 3-5 ounces per session, but it will vary depending on a lot of factors, like your baby’s particular needs and growth spurts. During these growth spurts, very common in this stage, your baby may need more milk, meaning you may want to adjust your pumping schedule temporarily to increase your supply.
For these changes, add pumping sessions whenever possible, especially in periods when your baby appears to be hungrier. You should pay attention to your baby’s cues and try to match your pumping schedule with their demand to meet their nutritional needs. Flexibility and attention to your baby’s behavior are important to respond to their needs appropriately and manage your milk supply through the developmental stages.
Older Infants (6-12 Months)
As your baby approaches the age of 6-12 months, solid foods are introduced into their diet, which affects both breastfeeding and pumping needs. This transition in diet usually means a gradual decrease in milk intake as the solids become more important in nutritional value. Yet, breast milk still provides essential nutrition and immune support during this period.
The amounts one pumps during this time will vary from 3-8 ounces per session, depending on the amount of solid food your baby is consuming. It’s normal to have fluctuations based on the types and quantities of foods introduced.
To ensure balanced nutrition, continue offering breast milk alongside solids. Aim to maintain a consistent pumping schedule that aligns with your baby’s feeding routine, allowing flexibility to accommodate changes in their appetite. Breastfeeding or offering expressed milk before meals can help ensure that your baby receives the nutrients they need from milk first. Monitor your baby’s growth and developmental cues to adjust accordingly, maintaining open communication with your pediatrician about any concerns.
How Can You Pump Effectively for Your Baby at Every Age?
To successfully pump through every stage of your baby’s life, here are some necessary tips that you should follow:
Pick the Right Pump and Gear
Choosing the right breast pump is a very important part of pumping effectively for your baby at every stage of their development.
● If you live a busy lifestyle or want to pump often, an electric wearable breast pump, such as the Momcozy All-in-one M5 Wearable Breast Pump, makes the process easier and supports a consistent milk supply for the growth of your baby.
● If you need more flexibility—for example, if you only need to pump occasionally or will be traveling—a manual pump is lightweight, easy to clean, and thus quite convenient as your baby gets bigger.
● Measuring your nipple size helps to ensure the pump flanges fit comfortably and will prevent discomfort that may lower milk production, thereby supporting effective pumping through all phases of growth in your baby.

Pump at Regular Times
Establish a regular schedule for pumping as this will help keep an adequate milk supply for the various stages of your baby’s growth.
● Try to align your pumping sessions with your baby’s natural feeding schedule; for instance, if they feed every three hours, aim to pump at similar intervals.
● Early in the months, be prepared to pump every 2-3 hours and include one nighttime session when prolactin levels, crucial for milk production, are highest.
● Once your baby starts sleeping for longer periods at night, you can slowly start to reduce the frequency of pumping to accommodate the changing pattern.
● Set reminders on your phone for those hectic days so that you remember to pump regularly.
Store Milk Safely
It is important to store expressed milk appropriately in order to keep it safe and nutritious for your baby.
● After pumping, transfer the milk into clean, BPA-free containers like baby bottles or storage bags designed for breast milk.
● Clearly label each container with the date and time of pumping using waterproof labels or permanent markers to keep track of freshness.
● Refrigerate the milk promptly, as it can be safely stored in the fridge for up to four days.
● Freeze milk in small portions (2-4 ounces) to minimize waste for longer-term storage. It is best used within six months to maintain the highest quality and nutritional value.
● Thaw frozen milk overnight in the refrigerator or by gently warming it in a bowl of warm water before use.
Pumping Made Simple: Ounces by Age for Your Little One
