My baby boy is 6 weeks old this week and he pees like an absolute champ, however his urine smells very strong and you can even smell it on his clothes when he's wearing a nappy that needs changing. I change him regularly and he doesn't have any signs of being unwell but my mother in law mentioned it could be a UTI which made me wonder. Anyone else's baby have strong smelling urine? He's been like it for weeks and i never particularly noticed it until my mother in law mentioned it, his urine is a normal pale yellow colour.
