How To Know If Baby Is Getting Enough Milk?

Fourth Trimester & Breastfeeding

Today we have special guest Naomi Hull talking to us all things breastfeeding. As big question on most mum’s lips is ‘Is my baby getting enough milk’. We don’t have amazing measuring devices on our breasts but there are many things you can keep an eye on.

Thanks Naomi!

As mums, we only want to do what is right for our baby and we also want to know that our baby is getting all that he/she needs.

Sometimes it can be hard to believe that our body can provide all that our baby requires for growth and nutrition, but rest assured in most circumstances your body will do what it is designed to do. Your body grew that baby, right? So why doubt that it can feed it as well?

So how can you be sure that your baby is getting enough??


‘It can’t come out if it isn’t going in’ is my motto.

Day 1 – 1 wet nappy

Day 2 – 2 wet nappies

Day 3 – 3 wet nappies

Day 4 – 4 wet nappies

Day 5 onwards – 5-6 heavily wet disposable nappies or 6-8 wet cloth nappies – these tend to get changed more frequently.

Bowel motions – after the initial sticky black meconium bowel motions, a breastfed baby will have runny, mustardy colour, bowel motions and may look grainy. There should be at least 1-2 runny poos a day or more in the first few weeks to months.

Sometimes it can be OK for a baby to miss a few days – so long as they are not distressed or irritable, and so long as there are still plenty of wet nappies.

Weight Gains

Babies who are breastfeeding do not gain weight at a consistent rate. They will have some weeks where they have large weight gains >200gms/week, and other weeks where it is not so great <120gms/week. This is why it is important to look at weight gains over a longer period of time, along with other measures, like nappies and the following dot points.

Weight gains can be impacted by the use of different scales, whether the baby has just fed, or even if they have just done a poo! So if you are going to weigh weekly please try to use the same scales, weigh naked, and take note of timing etc.

In general, you can look for around 120-150gms/week on average, and that their weight is plotting along within 1-2 percentile lines on the growth chart.

You can even judge by their clothing – are they filling out their clothes? Are they moving up to the next size? How many rolls on those thighs? How many chins?

General Contentedness

If your baby is generally happy and content and sleeps for some periods you can feel assured that they are getting enough milk – in the context of the output and weight gains.


Is your baby generally reaching their milestones? Once again taken into the context of all the other factors mentioned above.


Genetics plays a role here – are you and your partner tall? Slim? Large build? Slight frame? Chances are your child will follow.


As you can see there is so much more to consider than just the numbers on the scales. If you are worried about breastfeeding please check in with an IBCLC, for a thorough assessment and discussion. Sometimes it isn’t that you aren’t making enough milk or can’t make enough milk, there are other factors that can affect whether or not your baby is getting enough milk. But that is a whole other blog – so I’ll add it to my list 😉

My interest in infant feeding developed after the birth of my first baby in 2001. I realised that even though I was an RN my knowledge of how breastfeeding worked was very limited. So, I developed a strong desire to assist mothers to have access to up to date evidence-based information on infant feeding. I volunteered with the ABA and became a Breastfeeding Counsellor and then worked towards becoming an IBCLC (qualified in 2010). Since then I have worked as a Lactation Consultant in a maternity hospital, in my own Lactation clinic with a GP/IBCLC colleague, and in my own Private Practice. As an IBCLC I can provide antenatal education about intiating breastfeeding and the early days/weeks, Post-natal consultations for reassurance, discussion of supply, weight gains etc. I can assist you with positioning and attachment, damaged nipples, mastitis, breast pain. I can support you though illness, medications, and weaning or mixed feeding.I am available Monday to Friday between the hours of 9am and 4pm. I can come to you so long as you are within 15km of Ashgrove, otherwise by negotiation. I am also happy in some instances, to do consultations by Zoom or Skype, this would be ideal for follow up consultations or quick questions, or antenatal consultations when necessary. Feel free to give me a call if you aren’t sure if a lactation consultation is what you need, or if you’re not sure of what we do. I would love to chat and answer your questions.
