When does the milk expire?

When does your milk come in - and how does it feel? Find peace, understand your body's process, and learn what is completely normal in the first few days after birth.

Hvornår løber mælken til?

After childbirth, many eagerly await the moment when their milk "comes in."
But when does it actually happen – and what does it feel like?

It's completely normal to be unsure, especially if it's your first time.

What does it mean for milk to come in?

When we talk about milk coming in, it refers to the transition from colostrum to more mature breast milk.

In the first few days, the body produces colostrum, which is concentrated and nutrient-rich. After this, the milk supply begins to increase, and this is what many experience as "milk coming in."

When does it happen?

For most, it happens 4-7 days after birth.

However, the timing can vary. For some, it happens a little earlier, while for others it takes a little longer.

This doesn't necessarily mean anything is wrong.

What does it feel like?

When milk comes in, many will experience:

  • breasts feeling full and engorged
  • warmth or tingling in the breast
  • milk starting to flow more easily

For some, it's very noticeable, while for others it happens more gradually.

What affects the timing?

Several factors can influence when milk comes in.

These can include:

  • how often baby is latched
  • the birth process
  • if you've given birth before

The more the breast is stimulated, the faster the body will typically increase production.

What if the milk hasn't come in yet?

It's important to know that your baby gets what they need in the beginning – even if the milk hasn't "come in" yet.

Colostrum is tailored to your newborn and contains everything the baby needs in the first few days.

If you are in doubt, you can always have it assessed by a healthcare professional, such as a health visitor or lactation consultant.

How do you support the process?

You can help your body get started by:

  • latching the baby often
  • having skin-to-skin contact
  • creating a calm environment around breastfeeding

This signals the body to produce more milk.

When it feels different than expected

Some expect a very clear change – and become unsure if they don't feel it. But for many, it happens more quietly and gradually.

The most important thing is not how it feels – but how your baby is thriving.

What if the milk feels too slow?

If you feel that your milk hasn't truly come in, or that production feels low, it's a good idea to look at stimulation and feeding frequency. You can read more about how to support your body here: https://mybelly.dk/blogs/amning/oeg-maelkeproduktion
