Hi..Welcome to Practo If your baby is responding well to the medications its good, Was oflox in the drugs that are sensitive to the organism? If any urinary symptoms present and any slight fever persisting it means that infection might not have resolved. An Ultrasound examination of Abdomen and kidneys is mandatory in urine infection. If crying is because of pain in the genital area, your baby needs to be examined in that area of any local problem. If crying only in night that may be because of colic... Get your baby examined once to rule out any other problems and for an Ultrasound examination. Give plenty of fluids to her. Hope I could clarify. .. take care. ..
