Breast fullness vs supply

Breast fullness vs supply


My breasts feel empty, has my supply decreased?

Following the first few weeks of lactation, you may experience a rollercoaster of emotions and worry regarding your breastmilk supply. Firstly, with only small amounts of colostrum and a hungry baby – you worry, do I have enough? Then, often, the oversupply, engorgement, ice packs and sleepless nights, now you may feel you have too much! After all this settles, a few weeks have passed, now your breasts are soft once again, this is normal!

Even if your breasts do not feel full, there is a high possibility your baby is still receiving adequate amounts of breastmilk. In the first 4 weeks, your body responds to the number of times your baby breastfeeds, aiming to provide a supply that matches demand. Following these 4-6 weeks, your body establishes this supply-demand pattern, and your breastmilk production every 24 hours remains reasonably stable.

How do you know if your baby is getting enough breastmilk?:

  • Gulping and swallowing while breastfeeding
  • Producing frequent wet nappies daily
  • Normal, regular bowel movements
  • Baby settles following feeds
  • Gaining weight as to be expected for age

It is important to remember, your baby will lose up to 10% of their birth weight in the first week following birth. After 4-5 days, they should begin regaining weight until they are back to birth weight by 10-14 days of age. Following this, they should continue to gain weight, not lose.

What if you’re concerned about your breastmilk supply decreasing?

  • Check your baby’s breastfeeding attachment – ensure they are productive and suck/swallows evident.
  • Demand feeding – Instead of implementing a feeding schedule, allow your baby to breastfeed whenever they demand.
  • Avoid dummies – these may hide feeding cues essential to demand feeding.
  • Expressing - using an electric breast pump or hand expressing between feeds helps to increase your supply
  • Prioritise your mental health – try to reduce stress, eat well and drink plenty of water!
