It is important to express your milk to establish and maintain milk supply if your baby is not nursing at all or not nursing well. By expressing, you will also have your milk available to feed baby – every bit of moms’ milk that baby gets (even the tiniest amount) is like liquid gold.

When should mom start pumping?
- If baby does not nurse immediately postpartum, mom should begin pumping within 6 hours of baby’s birth — starting early makes a difference for future milk production.
What pump is best?
- If baby is not nursing, seriously consider renting a hospital-grade pump (such as those made by Ameda or Medela) that will allow you to pump both breasts at the same time. A hospital-grade pump is the best choice for maintaining or increasing milk supply.
- If you are not able to rent a hospital-grade pump, consider buying a pump (preferably a quality double pump) and/or hand expression.
How much milk should mom be pumping if baby is not nursing?
- Aim for pumping 750-800 mL (25-27 oz) per day by 7-10 days postpartum. If you have twins or higher order multiples, aim for pumping 800-950 mL (27-32 oz) by 14 days postpartum.
- It’s useful to evaluate mom’s 24 hour pumping output at 10 days. If supply is borderline (350-500 ml / 11-17 oz) or low (less than 350 ml / 11 oz), then galactagogues (prescription meds or herbs to increase supply) or other interventions should be considered.
- The research tells us that milk production at 2 weeks is an indicator of breastfeeding outcome, so it is important to get a good start. Even if milk production doesn’t start out well, however, don’t get discouraged–many moms will see an increase (even as late as 9-15 weeks after birth) if they continue with regular pumping.
How often should mom pump?
- 8-10 times per day: Until supply is well established, it is important to get at least eight good nursing and/or pumping sessions per 24 hours. Ten sessions per day is better, particularly if you have twins or higher order multiples.
- These sessions don’t need to be evenly spaced, but you should be nursing/pumping at least once during the night in the first few months or anytime you notice a decrease in supply. Avoid going longer than 5-6 hours without pumping during the first few months.
- When pumping during the night, milk yield tends to be better if you pump when you naturally wake (to go to the bathroom or because your breasts are uncomfortably full) than if you set an alarm to wake for pumping.
- If you are having a hard time getting in enough pumping sessions, adding even a short pumping session (increasing frequency even if milk is not removed thoroughly) is helpful.
How long should mom pump at each pumping session?
- If baby does not nurse at all:
- The first few days, before mom’s milk comes in, hand expression is often the most effective way to express colostrum. Double pump for 10-15 minutes per session for additional stimulation.
- Once mom’s milk is in, pump for 30 minutes per session, or for 2-5 minutes after the last drops of milk.
- If baby nurses but does not soften the breast well
- Double pump for 10-15 minutes after nursing.
- Empty the breast as thoroughly as possible at each session. To ensure that the pump removes an optimum amount of milk from the breast, keep pumping for 2-5 minutes after the last drops of milk. Use breast massage prior to pumping, and massage and compressions during pumping to better empty the breasts and increase pumping output.
- Rest & relax as much as possible.
- Skin-to-skin (Kangaroo care) can make a significant difference in pumping output.
- One study has shown that the moms of hospitalized babies who listened to guided relaxation or soothing music while pumping had an increased pumping output. When mom listened to a recording that included both music and guided relaxation while pumping, in addition to looking at photos of her baby, pumping output was increased even more. In this study, the interventions led to moms producing 2-3 times their normal pumping output. Milk fat content also increased for these moms in the early days of the study.

The effect of music-based listening interventions on the volume, fat content, and caloric content of breast milk-produced by mothers of premature and critically ill infants. Adv Neonatal Care. 2012 Apr;12(2):112-9.)
- If double pumping is difficult to coordinate in the beginning, then single pump, alternating sides. Move to double pumping as soon as you can.
- Avoid any medications that might interfere with milk supply (hormonal birth control, pseudoephedrine, ethanol/alcoholic beverages, bromocriptine, ergotamine, cabergoline)
- If supply is not increasing as expected by 7-10 days after birth, consider the use of galactagogues. Fenugreek, metoclopramide (Reglan) or domperidone (Motilium) can be helpful for increasing milk supply.

Note: Premature infants are certainly not the only breastfed babies who have problems nursing at the breast, but much of the writing and research in this area involves premature babies and their mothers. Talk to your lactation consultant about adapting these guidelines for older babies.
