Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.Forum.
Your 2 years daughter had abdominal pain
, with a gap of 30 minutes. the wind is smelly, and pain stops on passing wind.
The pain could be due to Vitamin medicines, new diet like veining foods, constipation
, infection etc.
I advise you to consult a pediatric specialist for diagnosis and treatment. She may have to use anti spasmodics, anti biotics, etc for relief.
Wishing her a quick and complete recovery.
