Water Infections

Hi ladies, I am quite worried about my little one. When he was 7 weeks, I noticed that his nappies were smelling really strong, so I took a sample to the doctor (was fun trying to catch it!) and it turned out he had a urinary infection. He is now 12 weeks and over the weekend his nappies ar starting to smell the same again, so I'll take him to see my GP tomorrow.

Has anyone else experienced this? I never thought that babies could get this so young!!!!!!
