How much pumped breastmilk at 3 months

During this period of time, your baby's sole source of nutrition is either breastmilk or infant formula. Water can be introduced at about 3 - 4 months. We do not recommend:

  • Starting any solids until about 4 months.
  • Giving juices until 6 months.
  • Giving Cow’s milk until 12 months.

Breastfed babies will feed every 2 - 3 hrs initially, and usually a feed will last about 20-30 minutes. You will know your baby is feeding enough if he or she is producing at least 4-5 wet diapers a day and at least 2 stools a day. Babies will feed every 3-4 hours at night time.

Babies fed infant formulas usually will feed every 3 - 4 hours during the day. During the first 2 weeks, babies will eat on average 1 - 2 oz at a time. By the end of the first month they eat about 4 oz at a time. By 2 months, increase to 6 oz per feed, and by 4 months, about 6-8 oz per feed. By 4 months, most babies are drinking about 32 oz in 24 hrs.

Feedings for your newborn vary between breastfed babies and formula fed babies. Please find additional information on breastfeeding and formula feeding below.

Breastfeeding

  • The number of daily feedings will vary with each baby. Your baby may breast feed every two to three hours on request. This may be 8 - 12 times a day.
  • Each feeding may last 20 - 30 minutes where you will breast feed 10 -15 minutes on each breast. Burp after the first 10 - 15 minutes and then continue to the second breast to finish the feeding.
  • There will be days where the baby will want to feed more frequent than every 2 - 3 hours, this is called Cluster Feeding. Cluster feeding is when a baby’s feeding schedule is more frequent and bunched together in a day. It is most common in the evening, although it may differ between babies. This tends to happen during your baby’s growth spurts. It is a way of your baby telling your body to start producing more milk because it is growing bigger.
  • Breastmilk contains all the needed vitamins and minerals except Vitamin D. Therefore it is recommended to give your baby a Vitamin D supplement. Please consult with your provider before starting any supplements.
  • Freshly pumped breastmilk can be stored at:
  • Room Temperature (66 - 78 degrees Fahrenheit): 4 - 6 hours
  • Refrigerator (39 degrees Fahrenheit or lower): 3 - 8 days
  • Freezer (0 - 4 degrees Fahrenheit): 6 - 12 months
  • To thaw frozen milk, place the bag or the bottle in the refrigerator. It will take a few hours to thaw. For quicker thawing, place it in a pan of warm water. Do this until it has warmed up to the temperature your baby likes.
  • Never warm up breastmilk in the microwave or boiling water. This destroys the protective antibodies in the breastmilk.
  • Remember to throw out any remaining milk in the bottle when your baby is done feeding.

Formula Feeding

Infant formulas are a safe alternative to breastmilk. Your provider will be recommending a formula for you when we see your baby initially in the hospital or at the office. Your baby will be on formula for the first year of life. Most infant formulas are available in ready to feed, powder, or concentrates. Follow the directions on the containers. Always make sure the bottle and nipples you use are clean.

  • Most babies will take 1 - 2 ounces of formula per feeding and will eat every three to four hours for the first 1-2 weeks. Give your baby about 20 minutes to eat. If your baby is eating 2 ounces in less than 15 minutes, then you may consider increasing the amount you give for the next feed. By the time your baby is one month old, he/she may be drinking 4 ounces at a time. Keep in mind that each baby has its own pace. Do not force feed your baby to finish the bottle. ALWAYS USE NURSERY WATER TO MIX FORMULA.
  • For all infants, use formula that has iron in it. This helps to prevent iron deficiency anemia. Iron-fortified formulas contain all the vitamins and minerals needed. Extra vitamins are therefore not needed for infants taking formula.
  • Formula Storage:
  • If you decide to prepare the formula ahead of time, make sure you refrigerate it. Formula that is refrigerated must be consumed within 24 hours.
  • Formula at room temperature should be discarded after 1 hour.
  • Leftover used formula should always be tossed. Reason: Contains germs that can grow.

Feeding your baby expressed milk

When should I start giving my baby expressed milk?

If your baby is healthy and breastfeeding is going well, there’s no need to rush into giving her expressed milk. For the first four weeks, you’re working together to initiate and build your breast milk supply while she learns to breastfeed efficiently. While there is limited data,1 it is thought that unnecessarily introducing bottles during this crucial first month could interfere with these processes.

But if your newborn struggles to latch or suck for any reason, then start expressing milk as soon as possible after the birth. Read our articles on overcoming problems in the first week and feeding breast milk to your premature baby or infant with special needs for more advice, as well as getting support from your healthcare professionals.

How can I feed expressed milk to my baby?

There is a range of expertly designed feeding solutions that can help you give expressed milk to your baby, depending on your and her needs.

For example, Medela’s innovative Calma teat will only allow milk to flow when babies create a vacuum by sucking. This means they can feed from a bottle using the same technique, tongue motion and jaw movement they would at the breast.2,3 Developed with breastfeeding experts from the University of Western Australia, Calma allows your baby to suck, swallow, pause and breathe just as she does when breastfeeding.4 By maintaining babies’ natural sucking behaviour, Calma is designed to make it easy to switch from breast to bottle-feeding and back again.

Medela also makes conventional bottle teats in two flow versions. And all our teats can be attached directly to the bottles you express milk into, minimising the risk of spillages.

If your newborn needs expressed milk, but you don’t want to offer her a bottle until she’s become used to breastfeeding, you could use a baby cup designed for short-term feeding. This allows your baby to sip or lap your expressed milk – be careful to avoid spills! It’s advisable to have a healthcare professional on hand the first time you use the baby cup, to make sure you’re both getting the hang of it.

For babies who need expressed milk supplements in addition to regular breastfeeding, a supplemental nursing system (SNS) can be helpful. This has a thin, flexible feeding tube that can be fixed alongside your nipple to give your baby expressed milk while you’re breastfeeding her. This allows your baby to stay at your breast longer, which further stimulates your breasts to help maintain your milk supply, and also helps improve her breastfeeding skills. It can be useful for mums with low milk supply or with adopted or surrogate babies.

If your baby can’t create the suction needed to breastfeed – perhaps because of a disability, congenital condition or weakness – you could try a feeder designed for babies with special needs. These allow infants who can’t suck to feed using gentle compression instead.

What’s the best way to introduce a bottle?

If breastfeeding is going well and you’ve decided it’s the right time to give your baby a bottle of expressed milk, follow these tips:

Take your time

Don’t wait until your big night out or first day back at work to introduce your baby to the bottle. Start trying with a small amount of expressed milk, in a relaxed and unhurried way, a couple of weeks beforehand. Gradually build up to giving a full feed of expressed breast milk from a bottle.

Pick your moment

Ideally your breastfed baby should be alert, but not too hungry, the first time she has a bottle of expressed milk, so that she is as relaxed as possible.

Delegate feeding duties

Your baby may be confused or frustrated when you offer a bottle, as she’s used to your breast. It might be easier if someone else gives the first bottle, and you stay out of the room so your baby can’t see or smell you.

Not too hot, not too cold

Your baby may be more likely to take the expressed milk if it’s around body temperature, ­37 °C (98.6 °F).

Dip and sip

Try dipping the bottle teat into some expressed milk before offering it, so it tastes and smells of your breast milk. Then gently stimulate your baby’s top lip with the teat to encourage her to open her mouth.

Positioning for bottle-feeding

Feed your baby on demand and cuddle her in a semi-upright position. Never bottle-feed her while she’s lying flat or prop her up with the bottle, in case of choking. Go at her pace, with as many pauses as she needs – you can even try switching sides during the feed.

Be patient

Don’t worry if she doesn’t take to the bottle straight away – it may take several tries. If she pushes the bottle away or becomes upset, comfort her and wait a few minutes before trying again. If she still won’t drink from the bottle, wait a few more minutes and then breastfeed her as normal. Try again with the bottle at a different time of day.

How much expressed milk should I give my baby?

Every baby is different. Research shows that in babies aged one to six months, one baby may take as little as 50 ml during a feed while another may take as much as 230 ml. Start by preparing a bottle with around 60 ml, and see if your baby needs more or less. You'll soon learn how much she typically takes – but don’t ever pressure her to finish the bottle. 

How can I ensure bottle-feeding is safe for my baby?

Always clean and sanitise your breast pump set and bottles according to the instructions, and wash your hands before pumping, handling milk or feeding your baby. Follow our guidelines for storing and thawing your expressed milk safely.

If warming your breast milk, place the milk bottle or bag into a bowl of warm water or a warmer, or run it under a warm tap (max ­37 °C or 98.6 °F). Never warm breast milk in the microwave or on the stove top.

Will my baby cope with switching from breast to bottle?

Mums sometimes worry that if they introduce a bottle too soon, their baby will get accustomed to the artificial teat and struggle to return to breastfeeding. Others are concerned about the opposite problem – if they don’t get their baby used to a bottle early she may never accept one later. Both of these problems are commonly referred to as ‘nipple confusion’.

Experts disagree on whether nipple confusion is really an issue.1 Certainly sucking from a conventional bottle teat that doesn’t require a vacuum to be created is less effort for a baby than sucking from mum’s nipple, as the milk flows more freely and gravity lends a hand. And some babies do seem to have a preference for breast or bottle, and never take to the other. But many babies switch happily between the two. 

If you’re still struggling to feed your baby expressed breast milk, speak to a lactation consultant or breastfeeding specialist.
