My 17mnth old has had very loose, watery stools for almost a week now. vomited a little yesterday morning too. no fever and seems otherwise fine. ???

Give them: clear liquids for 24 hours then if doing better advance diet to bananas, rice and toast for another 24-48 hrs then back to a normal diet. if it worsens or a fever begins contact their physician

Resolving gastro: Simplify his diet for a few days. Encourage hydration primarily with water, avoid juices and take it easy on milk for a period of time. Focus on foods that are easy to digest - plain oatmeal or oat cereal, apple sauce, dry toast, mashed potatoes without the butter/cream etc. That should help his poops become more formed while the gut is healing from being sick.
