My one-year-old daughter has an upset stomach. Should I give her probiotics such as yakult?

Is she having pain? Yakult is not effective to treat stomach pain as the good bacteria content is minimal and it's very sweet. http://afcoaching.com.au/blogs/blog/39799041-11-reasons-to-avoid-yakult-and-other-probiotic-drinks My daugther has upset stomach twice and we feed probiotics and not effective at all. Both times, we brought her to A&E as the pain is unbearable. PD prescribed debridat and she recovered.
