Wet Diapers: How Many Should Newborns Have Daily?

Newborns have tiny stomachs, no bigger than an almond, so they need to feed every few hours. They also need a lot of diaper changes! The number of wet diapers a newborn should have in a day is a good indicator of whether they are getting enough to eat and staying hydrated. In the first week of life, the number of wet diapers a newborn has will increase daily. On the first day, a newborn will probably pee once, so you can expect one wet diaper. By day two, this should increase to two or three wet diapers, and by days three to five, you should be seeing a significant increase, with three to five wet diapers. From day six onwards, your newborn should be producing at least six to eight wet diapers every 24 hours, but some babies will have even more.

Wet diapers indicate adequate nourishment and hydration

Wet diapers are a good indicator of adequate nourishment and hydration in newborns. Typically, a newborn will pee once within 24 hours of birth, so you can expect one wet diaper during this time. In the following days, as the baby consumes more milk, the number of wet diapers increases.

By the third day, newborns should produce a minimum of three wet diapers. This number increases to around six or more by the sixth day. From the first week onwards, a baby will typically have about four to six wet diapers per day. This indicates that the baby is getting enough nourishment.

Breastfed babies may not have many wet diapers during the early hours and days of life, as the mother's milk supply does not increase until the third or fourth day postpartum. Therefore, it is common for breastfed babies to have fewer wet diapers than bottle-fed babies during the first week.

It is important to monitor a newborn's urine output, especially if they are not feeding regularly. If a baby is not getting enough nourishment and hydration, they can become dehydrated, which is dangerous. Signs of dehydration include lethargy, excessive sleepiness, fast breathing or heart rate, no tears when crying, a sunken soft spot on the head, and dry skin.

To check if a diaper is wet, you can take it apart to examine the underlayers or gel material for moisture, or use a tissue to absorb the urine and make it easier to see.

A newborn's urine output should increase daily over their first week

A newborn baby will pass urine for the first time within 12 to 24 hours of birth. On the first day, it is normal to see only one or two wet diapers. This is especially true for breastfed babies, as the mother's milk supply does not increase until day two or three.

On the second day, the number of wet diapers should increase to two or three. Breastfeeding mothers should expect their newborns to have fewer wet diapers than bottle-fed babies.

By the third day, the number of wet diapers should increase to three to five per day. This is an important indicator that your baby is getting enough to eat and is well hydrated.

From the sixth day onwards, your baby should be producing at least six wet diapers every 24 hours. Some babies will have a wet diaper at every feeding, which is perfectly normal.

By the end of the first week, a typical peeing routine for a baby will result in about four to six wet diapers per day. This is a good indication that your baby is thriving and getting enough nourishment.

It is important to monitor your newborn's urine output, especially in the first week, to ensure they are getting adequate fluids and are not becoming dehydrated. Dehydration in newborns is dangerous and can be identified by signs such as cracked or dry lips and mouth, a sunken soft spot on their head, and a lack of tears when crying.

Dehydration in newborns can be dangerous

Newborns have small stomachs, so they need to feed every few hours. In the first week, a newborn will take between half an ounce and one ounce per feeding. It's normal for new babies to feed eight to 12 times every 24 hours.

By day three, newborns should produce a minimum of three wet diapers per day. By day six, this should increase to around six or more wet diapers per day. From day five onwards, a baby should have six or more wet diapers per day.

Dehydration means your body loses more fluids than you take in. Babies are more at risk of dehydration. If left untreated, it can become a serious problem. Newborns have tiny stomachs and can only drink a few teaspoons of milk at a time, so they need lots of regular feedings.

Common signs of dehydration in newborns include:

• A sunken soft spot on the top of the head
• Sleeping too much
• Crying with little or no tears
• Cold or discoloured hands and feet

If you notice any symptoms of dehydration in your newborn, call your doctor right away. Serious dehydration may require hospital treatment, where your baby will be given fluids through a bottle, a tube from their nose to their stomach, or a tube into a vein (IV).

To prevent dehydration, offer your newborn regular feedings of small amounts. If your newborn is unable to breastfeed, try different ways to deliver milk, such as pumping breast milk or using baby formula with a bottle or dropper. Dress your baby appropriately to avoid losing liquids through excessive sweating or shivering.

Urine colour can indicate underlying health issues

The number of wet diapers a newborn baby produces each day is a good indicator of whether they are getting enough milk. Typically, a newborn will pee once within 24 hours of birth, so you can expect one wet diaper. In the following days, as the baby consumes more milk, the number of wet diapers increases. By the end of the first week, a typical peeing routine for a baby will result in about four to six wet diapers per day.

The urine of healthy newborns is usually clear and slightly yellow. However, the colour of urine can vary and indicate underlying health issues.

Pink urine

Pink urine is commonly seen in newborn babies and is caused by the presence of pyruvate crystals, which are visible in the first 3-5 days after birth when babies are not yet gaining weight. These crystals disappear as the infant takes in more milk. It is important not to confuse these crystals with blood, as they will stay pink, while blood will oxidize and turn dark maroon or brownish.

Dark yellow urine

Darker yellow urine indicates concentrated urine, which may mean that the baby is slightly dehydrated. However, this could also be due to certain foods, food dyes, herbs, or vitamin supplements in the mother's diet, which can add a tint of green, pink, or orange to the urine.

Red, orange, or brown urine

A reddish, orange, or brown hue to the urine may indicate the presence of blood, which is not normal and usually means there is a problem. This could be caused by high levels of minerals in the urine, hereditary conditions, or immune system abnormalities.

Cloudy urine

Cloudy urine, especially with a colour change, could indicate a urinary tract or kidney infection.

"Brick dust" urine

A red-brown hue in the urine, often described as "brick dust," is caused by urate crystals, which are more common when a baby is dehydrated. These crystals will disappear once the baby consumes more fluids and nutrients.

If you notice any persistent changes in the colour of your baby's urine or other concerning symptoms, it is important to contact your healthcare provider for further evaluation and guidance.

A newborn's urine output can be affected by their diet

By the third day of life, newborns should produce a minimum of three wet diapers. As the days go on and the mother's milk supply increases, the baby will produce more urine and have more wet diapers. By day 4, the baby should have 4-6 wet diapers per day. On day 5 and beyond, the baby should have 6 or more wet diapers per day.

The amount of urine that a newborn produces is directly related to the amount of fluid they take in. If a baby is a good eater and takes 2 ounces of formula every three hours, they will have more wet diapers. If a newborn is sleepy or not taking in much fluid during the first day or so, they will have fewer wet diapers.

Breastfed babies may have fewer wet diapers than formula-fed babies because breast milk is more easily digested and absorbed by the body. However, this does not necessarily mean that they are not getting enough to eat. As long as the baby is feeding 8-12 times in 24 hours, gaining weight, and producing some wet diapers, they are likely getting enough milk.

After the first week, a baby should have at least 6 wet diapers per day to be well-hydrated. If they have fewer than 6 wet diapers a day or are producing very dark yellow, concentrated, and smelly urine, they may be dehydrated. Dehydration in newborns is dangerous and can lead to health complications. Therefore, it is important to monitor a newborn's urine output and contact a healthcare provider if there are any concerns.
