My daughter is 3.5 yrs old. She started with an episode of loose motions and vomiting 3 days back. She was diagnosed with stomach infection and put on antibiotics. Her loose motions have stopped but she still has the vomiting sensation. She has still not started her normal diet back. Most importantly, since a month, she has been complaining of headache and most prominently during the last few days. Can you please help. Do such young children suffer from headache and that too for so long. Also, for how long will the vomiting continue.
