Hi, my nearly 3 year old son was sick just the once on sunday and straight away after was asking for food with no ill effects of being ill, ate fine for the day etc all be it not too much and very sleeply. He was ok on Monday, Tuesday, Wednesday eating ok (not as much as normal) but still quite sleeply, then again on thursday morning he was sick the once again, he brought up his lunch from the day before. Again he straight away asked for food and showed no signs of just being sick. He has been eating ok again and is still also a bit sleeply. He is generally fit and health and eats perfectly fine. I have also noticed his tummy felt a little hard this morning. Do you have any suggestions??

Welcome to the ChatDoctorI completely understand your concerns but don't worry. The problems in your child could be due to worm infestation or mild bowel dysfunction. Sometimes, self limiting viral illness can also present like this. You may take the following measures to help him out:1. Rule out any constipation or bowel dysfunction. If present, go for a proper treatment. Lactulose will be useful for constipation.2. Give him a dose of Albendazole for worm infestation. 3. A healthy diet with plenty of fluids are useful.4. Start him on probiotics for the next few days.5. Also, start an antacid for any gastritis if present. If still, the problem persists, check with a pediatrician to rule out urinary tract infection, acariasis or liver dysfunction. Also, rule out any stressors. Hopefully this will help you.
