my 3 year old son got sick tuesday afternoon with a stomach ache and nausea. he vomited a few times that day and was very cranky and crying a lot throughout the night. he had diarreah a couple times but non since wednesday morning. he has been getting tylenol every 4 hours for his fever which was 101 yesterday. he has been sleeping a lot. he woke up for about an hour this morning and is already back to sleep. he looks pale and seems very weak. he has barely ate anything since tuesday morning. i m worried that he s sleeping so much. he s normally very against napping in general.
Vomiting, fever and diarrhea suggests that he has gastroenteritis which is the infection of the intestine usually caused by a virus.  The pallor, weakness and sleepiness suggest he has moderate to severe deny Chat Doctor.  The treatment of gastroenteritis is fluids therapy like ORS but in your children case you must rush him to the hospital because he will need intravenous fluid because he is intolerant to oral fluids. I suggest doing serum electrolytes also in the ER. I hope this helps
