Good morning doctor. My baby is 4 month old and now he is going urine 3 or 4 times for a whole day, it is in yellow colour with baby pink colour spots, is any problem?

A. Brick Dust Urine Very concentrated urine during the first few days of life can contain urate crystals (uric acid crystals). These urate crystals can cause a pink, red, or orange-colored, powdery stain in your baby's diaper called brick dust. 7 It might be scary, but brick dust is normal for many newborns.
