Hi Robin
good for you for asking such a hard question. My 5 year old still forgets to wipe herself on occasion and is smelly. I have also found that I cannot use bubble baths or soaps down there. This helps tremendously.
If she isn't in any pain when she pees or constantly trying to pee most likely it isn't a UTI. Also, more water can't hurt to help keep her flushed out.
I hope it is this simple.
