I noticed my baby's urine is very dark and has a strong smell when I change diapers. Is this a sign of an infection or dehydration?

Dark-colored and strong-smelling urine in babies most often indicates dehydration rather than infection. When a baby isn't getting enough fluids, her kidneys concentrate the urine, causing both the dark color and strong smell. This is especially common in hot weather, during febrile illness, or during the transition to solids.
Urinary tract infection (UTI) can cause similar symptoms, but usually there are additional signs like fever, fussiness, poor feeding. In babies under 6 months, it's harder to tell these conditions apart.
What to do:
- First, increase breast milk/formula intake: if the urine doesn't become lighter within 24 hours, keep monitoring.
- If the dark color and smell last longer than a day, your baby has a fever (≥38°C), she's fussy or vomiting, or urine output is noticeably decreased (dry diapers for 8+ hours), definitely contact your pediatrician.
- If the strong smell is accompanied by blood in urine (pink/reddish color) or your baby cries in pain while urinating, this also suggests UTI and needs doctor evaluation.
