Mom & EBF baby diarrhea...

For about 5 days now I myself have been having an upset stomach and diarrhea. The day after I noticed mine, I started seeing diarrhea from my 4mo old baby as well. She seems to be eating and acting normally, other than the fact that her poo is liquid and she'smore gassy than usual. The only thing I can think of is that its either something I ate is getting to her through my breastmilk, or it's because we ran out of her probiotics and her gut is freaking out. I'm not really sure where to go from here or what I can do to get my babe back to normal. We started the probiotics again 3 days ago and I'm waiting to see a change. Is there any point where I should call the doctor? I've always heard as long as they're eating and staying hydrated that it'll pass....
