what your baby’s urination says about your feeding routine

Being a new parent can be scary. Here you are staring at something you’ve created, not yet able to communicate with each other. How do you know your baby is getting enough milk to help them feel satisfied, comfortable and grow? Well fear not, paying attention to their urination and bowel movements can tell you an enormous story. Read on for the quick facts about what to look for.

Urination Quick facts

To know who well your baby is feeding, you want to pay attention to:

  • frequency,
  • colour, and
  • smell.


The amount of urination your baby puts out is definitely a good indicator of whether your baby is getting sufficient milk. On average, you should expect your baby to pass about 20mls and 30 mls of urine on the first day of life. This will gradually increase to between 100 mls and 200mls by the end of the first week.

So, how do you know how much this is? Well, think of it this way. As a general guideline, for the first 6 days of your baby’s life, he or she will have one wet nappy per day. So day one of life is one nappy. Day two is two nappies. Day three is three nappies. etc.  After that, you should expect six to eight nappies per day.

At around 6 weeks, you will notice the nappies getting progressively heavier as the weeks pass by and a larger quantity is dispelled per pee. This is because your baby bladder has become large enough to hold more volume.

How do you know how much volume is in the nappy? You can get a rough guide by taking a nappy and pouring 30 mls of fluid into it.  Feel how heavy the nappy is? That’s what you are expecting from your newborn.

Colour and smell

Regardless of age, urine should be pale in colour and not contain a strong odor. The darker the colour and the stronger the odor may be a sign of dehydration or other problems. If you are worried, check with your caregiver.

You can take a sample by using a sterile Paediatric urine collector.

What does all this mean?

To ensure your baby is getting enough milk, make sure that:

  • he or she is filling 6 to 8 nappies per day after the first week of life,
  • the colour of the pee is pale and not very noticeable in the nappy, and
  • there is no offensive smell to the nappy.
