So I just received the results for her second sample and she definitely has a uti. Still no fever or any other symptoms apart from the smelly urine. She has a cold at the moment but that's obviously not related.

I hate that I have to give her antibiotics now. She's only 5 months. Am I going to completely stuff up her gut now?

It's not like I can even give her cranberry juice or anything either because of her age.
