Does your little one cry or complain about pain while urinating, or seem to be wetting more diapers than she usually does? Or has she stayed dry for much longer than usual? These could be signs of a urinary tract infection (UTI) and you should take her to the doctor, says the American Academy of Pediatrics (AAP).
You should also look out for episodes when she passes urine that is cloudy, bloody or has a strong foul smell, or wets herself if she already knows how to use the toilet. Other signs include fever, vomiting, tummy pain and lethargy, as well, says Dr Oh Meng Choo, a paediatrician at Kids Clinic, a Singapore Medical Group paediatric clinic.
But many of the signs can be easily missed in young children. About one in 20 babies can have fever without other common UTI symptoms. This lack of signs is why this infection often goes undetected in infants, the AAP notes.
