#asktheexperts My daughter is 2 yrs old. she had urine infection last week, blood traces were found in her urine and it was acidic. doctor had to say it can be because of hard urine , like some crystal formation in urine and she needs to increase her water intake. As such she has enough water during the day. What else could be the reason for hard urine? What precautions I need to take in her diet other than increasing water intake?
