Hello. This is Dr Rubal Jain (MD Pediatrics and Lactation Consultant)
This intermittent upset stomach could be because of a change in weather, water, her food habits or start of an infection.
Will need more details. Do not overuse Ondem as it is only taking care of the symptoms and not the root problem.
Till then I would advice you to keep up the fluids in the form of water, ORS, buttermilk, coconut water etc and only give freshly prepared semi solid home made food.
