How to tell if my son has uti. been screaming days straight, not eat or taking bottle, fighting sleep. doesnt want to e put down hes 10 months?

Hard to say: You have omitted important data. Circumcised males rarely have UTI's, uncircumcised males would have their 1st before 2 months of age. Either would also have fever.A 10 mo old falls into the developmental stage where they have anxiety around strangers and fear separation.At this point I would visit with his doc to rule out a treatable problem.
