My dd has not been well since Sunday. She has a stomach ache and been vomiting once or twice daily, mostly in the mornings after having a few sips of water. She was first seen by a doctor who said it's a stomach bug. She is still vomiting so I took her to be seen again yesterday. This time the doctor agreed it's a stomach bug but because my dd has not been passing stool since Sunday, he said this could also contribute to the vomiting. He has prescribed lactulose and this is the second day of taking it. My dd has been passing runny poo which I think it's leaking around the hard impacted poo. I am giving her lots to drink and going to put her in a warm baking soda bath. What else do you suggest? Please help. I'm not too sure if it's a stomach bug as no one in our family is affected so constipation is more likely.
