How Breast Pumping Helps Increase Milk Supply.. 

Breast expressing is one of the many and best ways to help encourage and boost your milk supply in the first weeks to months of breastfeeding.  Expressing will also help you understand your personal supply and help maintain your milk supply later on when your baby is sleeping through and not feeding at night. 

It’s an opinion that expressing can interfere with your natural milk supply, this is absolutely correct but in a positive way.  

With supply and demand the demand comes first and supply a few days to weeks later. The first six weeks of your baby’s life is the fastest rate of growth, which means your growing baby will increase milk intake on a weekly basis with some babies reaching their maximum intake of milk per feed at 6 weeks.  To help keep up with this rate of growth, a combination of plenty of rest, good diet, active feeding, lots of fluids and expressing at the right time of day (so as not to interfere with feeds) will help your breasts to keep up with your newborn’s increasing demand. 

Finding the right breast pump can be a little tricky as one size or suction doesn’t fit all. Electric pumps are best; my rated pumps are the Lansinoh double which has the added benefit of a timer or Medela freestyle.  The Dog’s of all pumps which is the best for efficiency and stimulation is the Medela Symphony hospital grade which is available for rental only in the UK. There are a few pumps which are popular which I wouldn’t recommend and I’m sorry to name and shame but… the Elvie won’t help boost your supply, won’t fully drain or stimulate and has a history of breaking. The Hakka which is handy when you need to release a little milk ahead of a feed is also not a stimulating milk boosting pump. The Medela swing also isn’t great at extracting. 

It’s important you use the right size funnel, or flange as they call them in the States…flange means something completely different in the UK! As your breasts grow you may need to change the size of the funnel. Note: If you have friction around the nipple then you could be using the wrong size. Try smearing a little Vaseline around the inside of the funnel.

Expressing at the right time of day is important, so I recommend expressing straight after or within twenty minutes of finishing a day-feed. This tricks your breast into thinking your baby is still demanding more milk and will stimulate the breast into producing more milk. Plus, draining your breasts will reactivate an increase in milk supply. Expressing during the day helps your breast get into a routine of supplying more milk during the day rather than at night. Yes, your breasts can get into a routine and you may find they automatically start to fill with milk and you feel the let down just before or at the time of your scheduled feed. 

In theory at night, if you have slept and fed baby less you will store milk whilst sleeping, you will then be at your highest point of supply in the morning. 

Once your baby is sleeping for a period of five to seven hours during the first part of the night, I always encourage to express after the first two morning feeds and then in the evening just before you go to bed. This will keep the milk supply tip top and ensure you can sleep comfortably undisturbed by bursting breast until baby naturally wakes up later on in the night.

Expressing No-No’s…

1. Do not express before or between a feed as you will be extracting milk produced for your baby’s next feed. 

2. Do not sit pumping for hours on end. Focus on when and how much you are expressing so you can use the pump efficiently for the minimal amount of time. How your breasts work with milk flow and supply is personal to you so getting to know your breasts is crucial. Pump for 10 minutes with a double pump or 20 minutes with a single pump, the time taken to express speeds up as the weeks go by. Around week 4 to 6 milk thins and expressing takes less time.  By week 12 it may take you as little as 5 minutes!

3. Do not over express. If you have the supply of a dairy cow, express only after the first morning feed and just before you go to bed around 8-9pm, unless your second breast is rejected then you need to express the second side. 

For successfully establishing a good milk supply, expressing is only part of the plan. 

  1. Active feeding. 

Making sure your baby sucks well at the breast and doesn’t comfort suck and fall asleep. Nothing will stimulate your milk supply and drain your breasts like your baby can but unfortunately newborns tend to fall asleep easily when feeding! 

  1. Rest and sleep when your baby sleeps and go to bed early while you are still getting up for night feeds. Aim for 7/8 hours overnight and a daily nap. 
  2. Eat and drink well! Eat between each breastfeed and drink at least 2 but ideally 3 litres of water a day.
  3. Skin to skin nap. 
  4. Drink Fennel tea
