Baby diarrhea

Hi mommys

So my baby girl just completed 1 year , she’s been having diarrhea for 1 week now.

I already took her to the pediatrician and he examined her and took a stool sample and everything was fine.

But until now the diarrhea didn’t stop 😓 , is it normal? And how long should a diarrhea last ?

Should I take her to the doctor again? Should i be worried?

Note that she is eating & drinking very well and I didn’t introduce any new food for her.

Thanks ♥️
