Crystals in a 4-month-old's urine are usually harmless urate crystals, appearing as reddish-orange "brick dust" from concentrated uric acid, common when babies are dehydrated or not feeding enough, but if they persist past the first few days/weeks or if the baby shows signs of dehydration (dry mouth, fewer wet diapers, lethargy), you should contact a pediatrician to rule out other issues, as it can indicate dehydration or, rarely, underlying problems.
In the first few days after birth, you may see orange, pinkish, or chalky urine in your baby's diaper (this can be more common in boys). This isn't blood but urate crystals and is completely normal. These crystals develop because babies' urine is concentrated until they start taking in more fluids.
“Brick Dust” Baby Pee
It's usually not blood, but urate crystals, and often appears when babies aren't getting quite enough fluids. It should clear up with more breast milk or formula.
Urate crystals are more common when kids are dehydrated, but are also common in healthy, well-fed babies. The inner lining of the diapers can also contain moisture-absorbing crystals that sometimes leak out if there is a little tear in the diaper. Urate crystals are not painful to babies.
In summary, urate crystals are common and likely not a cause for concern. Monitor your infant's urine to make sure that they are urinating an appropriate amount to rule out dehydration. If urate crystals continue past an infant's earliest days, it may be appropriate to consult your pediatrician.
However, the most common cause of “blood” in the diaper is usually a normal condition caused by urate crystals. Urate is a normal waste product in the urine which can crystallize leading to reddish-orange stains in the diaper. This is not true blood and is no cause for concern.
When your child's urine has high levels of these minerals and salts, they can form kidney stones. Kidney stones can also be caused by certain medications, diabetes or problems with how the urinary tract is formed. Although kidney stones are not common in children, they have been on the rise in recent years.
Having a few small crystals in your urine is normal, and they usually don't cause problems. But large amounts of certain types of crystals may be a sign of a health condition that needs treatment. Some types of crystals may stick together and make kidney stones.
The 7 key danger signs for newborns, often highlighted by organizations like the WHO, are not feeding well, convulsions, fast breathing, severe chest indrawing, lethargy/unconsciousness (movement only when stimulated), high or low temperature, and jaundice (yellow skin/soles) or signs of local infection like an infected umbilical stump, requiring immediate medical attention.
There are many things that can cause crystals to form in urine. They include: Dehydration (not drinking enough water). Eating large amounts of certain foods, including protein, salt, fruits and vegetables.
Healthy urinary frequency in babies varies widely; some babies may urinate every one to three hours, while others do so only four to six times a day. But in general, you'll want to look for around six wet diapers each day.
To help prevent uric acid stones, cut down on high-purine foods such as red meat, organ meats, beer/alcoholic beverages, meat-based gravies, sardines, anchovies and shellfish. Follow a healthy diet plan that has mostly vegetables and fruits, whole grains, and low-fat dairy products.
In a healthy child, urine is light to dark yellow in color. (The darker the color, the more concentrated the urine; the urine will be more concentrated when your child is not drinking a lot of liquid.) In the first week after birth, you may see a pink or brick-red stain on the diaper, often mistaken for blood.
Your infant may have a urinary tract infection if any of the following symptoms exist: Fever of 100.4⁰F or higher. Crying during urination. Cloudy, foul smelling and/or bloody urine.
Supportive care includes increased fluid intake and dietary modifications. Medical treatment is dependent on the cause of the urinary stone disease. The morbidities associated with pediatric urolithiasis can be prevented by early diagnosis, detailed metabolic analysis, regular follow-up and medical treatment protocols.
Normal Urination in Breastfed Infants:
By DOL 5, your baby should have 6 or more wet diapers/day. (passing urine every 4 hours). From 1 week to 12 months of age, babies normally pass urine every 2 - 4 hours.
Crying, irritability, or twitching which does not improve with cuddling and comfort. A sleepy baby who cannot be awakened enough to nurse or nipple. Any signs of sickness (for example, cough, diarrhea, pale color). The baby's appetite or suck becomes poor or weak.

Cystinuria is caused by too much cystine in the urine. Normally, most cystine dissolves and returns to the bloodstream after entering the kidneys. People with cystinuria have a genetic change that interferes with this process. As a result, cystine builds up in the urine and forms crystals or stones.
These crystals are pleomorphic, most often appearing as rhombic plates or rosettes. They are yellow or reddish-brown and form only in an acid urine (pH 5.5 or less). Courtesy Gary C Curhan, MD, ScD.
The number one thing you can do is to drink enough fluids, like water. Drinking enough fluids will make your urine less concentrated and make it harder for crystals to form. Drink enough fluids so you pee about 2½ liters (or about 85 ounces) each day.
Kidney stones are also known as renal calculi or nephrolithiasis. They typically occur in adults, but can affect children as well and can occur even in babies. Kidney stones form when high amounts of certain substances accumulate in the kidneys, forming crystals or a stone.
If you notice urate crystals after the first few days of life, talk to your baby's doctor. They may ask you about feedings and weight gain, your milk supply if you're nursing, and signs of dehydration in your baby – such as decreased saliva, dry lips, going six hours without a wet diaper, and lethargy.
Sediment in the urine happens when crystals, bacteria, or blood exit through the urine. It can be the result of dehydration, urinary tract infections, or other conditions.
