Hello. Thank you for choosing healthcare magic. I m sorry to hear that about your daughter. Before her nap last sunday, was she well? How was her food intake before that incident? Is she the only one in the family who is vomiting? The most common cause of vomiting in children is still infectious gastroenteritis caused by virus or what we call stomach flu. It usually begins suddenly and resolves with in 1-3 days. For this case, you just have to monitor for dehydration. For mild cases of dehydration like feeling thirsty and slightly dry mouth, you can give oral rehydrating solution or pedialyte. Give this in small frequent sips because we don t want to induce vomiting especially if the stomach is still recovering from the infection. For persistent vomiting with moderate to severe cases of dehydration like dry mouth, sunken eyes, decrease in urine, or lack of tears, you have to bring your child to the hospital immediately for intravenous hydration. Viral infection, changes in diet and dehydration can cause stools to be hard thus there s difficulty and pain in passing it out. Have you noticed if your daughter s tummy is getting bigger or bloated the past days? For cases of vomiting with no bowel movement, we would also want to rule out any intestinal obstruction. Is their relief of the stomach ache after the vomiting? If the stomach ache is getting worse I suggest that you have her examined by your doctor first before giving her any suppository or medication. I hope I was able to help you. Regards, Hannalae Dulay-See, M.D. Pediatrics
