Hi. Agree that their are questions here. I'd say that it is time to take the child to the pediatrician. Urine in the blood can be related to kidney issues as well and you would want to address that. good luck
How do you know it is blood has the child's urine been tested ...how old is the child , what foods and drink is he/she eating drinking as this can also affect the color of the urine ,.has the child been involved in any accident recently ? I hope he/she is okay..let us know ...
