My baby boy (4 months) was Weeing out green mucous, no other symptoms, fine in himself. trip to the doc who tested his urine confirms nitrates present so he needs antibiotics. She says he will need a follow up scan. I’m a little concerned as I didn’t think it was very common for boys to get UTIs, let alone as young as 4 months. Has anyone had experience of a baby so young having a uti? Did they refer you for a scan and what were the results? Any idea what they are checking for?
