Newborn Babies And Excessive Urination: What's Normal?

can a newborn baby pee too much

Newborn babies urinate frequently, and it can be challenging for new parents to determine if their baby is peeing too much. On average, newborns can urinate up to 20 times in 24 hours, and this is considered normal. However, it's important to monitor your baby's urine output to ensure they are getting adequate fluids and eliminating waste properly.

In the first week of life, the number of wet diapers a newborn produces will gradually increase. By day 3, newborns should have a minimum of three wet diapers, and by day 6, this number increases to around six or more wet diapers per day. After the first week, a healthy newborn should continue to have at least six to eight wet diapers every 24 hours.

If you are concerned about your newborn's urination patterns, it's always best to consult with a healthcare professional. They can provide guidance and advice based on your baby's specific needs and development.

How to check if a newborn is urinating enough

Newborns pee quite frequently, with some sources suggesting they can urinate anywhere between 1-6 hours, or 4-8 times a day. Other sources suggest that newborns can pee as often as every 1-3 hours or as infrequently as every 4-6 hours. In their first month, newborns can pee up to 15 times a day.

  • Check the number of wet diapers: In the first 24 hours after birth, a newborn will probably pee once, so you can expect one wet diaper. In the following days, as the baby consumes more milk, the number of wet diapers increases. After about a week, a typical peeing routine for a baby will result in about four to six wet diapers per day.
  • Monitor the colour of their urine: The urine of healthy newborns is light to dark yellow in colour. Darker shades indicate concentrated urine, which may mean that your baby is slightly dehydrated.
  • Monitor the smell of their urine: Strong, foul-smelling pee may indicate a bacterial infection, such as a urinary tract infection (UTI).
  • Monitor their behaviour: If your baby is lethargic, very sleepy, or sleeping for four or more hours at a time, it could be an indication that they are dehydrated.
  • Monitor their health: If your baby has a fever, or is experiencing hot weather, their urine output may drop by half, which is normal. Once their health improves and the weather cools, they will likely return to their typical peeing routine.

If you are concerned that your baby is not urinating enough, contact your healthcare provider.

What colour should a newborn's urine be?

A newborn baby will pass urine for the first time within 12 to 24 hours of birth. In the first few days, a newborn's urine will be darker and more concentrated, and it may also have orange stains (urate crystals) in the diaper. This is normal for the first two days.

From the first week onwards, a newborn's urine should be clear, colourless, or light yellow. However, if you're breastfeeding, you may notice slight colour changes. Certain foods, food dyes, herbs, and vitamin supplements can change the colour of breast milk and add a tint of green, pink, or orange to your newborn's urine.

Concentrated urine is very dark yellow and may have a strong smell. After your milk comes in, a diaper with concentrated urine is okay occasionally. However, if your baby frequently has very dark yellow urine, contact a healthcare provider.

Both boys and girls can have a little blood in their diapers, but for different reasons:

  • Pseudomenstruation: Baby girls may have blood-tinged vaginal discharge during the first few days of life due to hormones.
  • Circumcision: Baby boys may have a small amount of blood in their diapers after circumcision, which should last only a few hours.

If you see any blood in your baby's urine or your child is crying and showing signs of painful urination, contact your baby's healthcare provider right away.

How many wet diapers are normal for a newborn?

Newborns typically urinate very frequently, and the number of wet diapers per day can vary depending on various factors such as their diet, intake, and individual bladder capacity. Here is a guide to how many wet diapers are normal for a newborn:

The First Week of Life

During the first week of life, the number of wet diapers a newborn produces will gradually increase. On the third day of life, newborns should produce a minimum of three wet diapers. By the sixth day, this number increases to around six or more wet diapers in 24 hours.

After the First Week

After the first week, a newborn's urination pattern should settle into a more consistent rhythm. From the second week onwards, a healthy newborn should produce a minimum of six to eight wet diapers every 24 hours. Some newborns may even pee up to 10 or 20 times a day, which is still considered normal.

Factors Affecting Urination Frequency

It's important to remember that all newborns are different, and their urination patterns can vary. Here are some factors that can influence the number of wet diapers:

  • Feeding method: Breastfed newborns may have fewer wet diapers during the early days before the mother's milk supply increases.
  • Age: As newborns grow older, their bladder capacity increases, leading to fewer wet diapers.
  • Diet and intake: The type of diet and the amount of fluid consumed can affect urination frequency.
  • Temperature: Some believe that being too cold may cause newborns to pee more often.

In summary, a healthy newborn's urination pattern typically establishes itself within the first week of life, with six to eight wet diapers being the norm after the initial days. If you have any concerns about your baby's urination frequency, colour, or any other related issues, it is always best to consult a healthcare professional.

What to do if a newborn is peeing too much

If you think your newborn is peeing too much, there are a few things you can do to address the issue and ensure your baby's health and comfort. Here are some detailed instructions and suggestions:

  • Monitor Urination Frequency and Amount: Keep track of your newborn's urination pattern, including the number of wet diapers per day. This will help you identify any deviations from their usual routine.
  • Check for Other Symptoms: Besides frequency, pay attention to other factors such as the colour, odour, and amount of urine. Dark yellow, concentrated urine with a strong smell may indicate dehydration. Blood in the urine or a bloody spot on the diaper is also a concern and should be addressed by a healthcare provider.
  • Maintain a Diaper Change Routine: Change your baby's diaper frequently, especially after bowel movements. This will help keep them dry and comfortable, reducing fussiness caused by wetness.
  • Consult a Healthcare Provider: If you have concerns about your baby's urination, don't hesitate to contact your healthcare provider. They can assess your baby's overall health, rule out any potential issues, and provide guidance on proper care.
  • Address Potential Causes: In some cases, frequent urination may be a sign of an underlying condition. For example, urinary tract infections (UTIs) or diabetes could be a factor. Consult your doctor if you suspect any health issues.
  • Ensure Proper Feeding: Adequate feeding is crucial to your baby's health. Ensure your baby is feeding well and getting enough milk. If you have concerns about their feeding habits or weight gain, consult a healthcare professional.
  • Maintain a Comfortable Environment: Keep your baby's room at a comfortable temperature, as being too cold could be a factor in frequent urination. A calm and soothing environment can also help reduce fussiness and crying spells.
  • Consider Different Diaper Options: Try using cloth diapers or disposable diapers with a wetness indicator. Cloth diapers may provide more comfort and allow you to gauge wetness more easily.
  • Practice Good Hygiene: Maintain proper hygiene practices, such as cleaning your baby's diaper area from front to back and washing your hands before and after changing diapers.
  • Monitor for UTI Symptoms: Keep an eye out for signs of a UTI, such as fever, vomiting, blood in urine, lower back pain, urinary incontinence, loss of appetite, diarrhoea, or a burning sensation during urination. Consult a doctor if you notice any of these symptoms.

Remember, it's important not to self-diagnose and always seek professional medical advice if you have concerns about your newborn's health and well-being.

On the second day, you should see at least two wet diapers. If your baby is not producing enough urine, ensure they are feeding regularly. If your baby is not feeding well, contact your healthcare provider.

Days 3-5:

Your baby should be producing at least three to five wet diapers during this period. If your baby is not meeting this milestone, it may be a sign of dehydration. Contact your healthcare provider if you notice any of the following:

  • Your baby has fewer than six wet diapers each day.
  • Your baby is producing small amounts of very dark yellow, concentrated, and smelly urine.
  • Your baby is unusually sleepy and difficult to wake.
