<s>[INST] My 4 months old (premature baby) breast fed son is suffering from loose stools & his potty is green color.  Doctor gave him Rinifol one in a day 2.50 ml & Econorm sachet daily for 3-5 days. He told me that its just a stomach infection. Whether its any serious thing?  Also my sons head is always warm than his body. [/INST] Thank you for your consulting in Heath care Magic. Color of stool is not normal, it should be yellow and consistency like as milk cream. Your doctor prescribed good treatment, but we don't know what kind of infection he has and has he inflammation in intestine. That's why I advise you please do stool analysis for excluding gastroenteritis and stool culture for flora and sensitivity to antibiotics. You should buy sterile container with small spoon inside for stool analysis at the chemist shop, take from 3 different place from diaper, you should take fresh stool only in the morning and give it in sample collection center in laboratory.
