Child Is Not Having Normal Stools. Due To Gastrointestinal Infection Or Intolerance To The Formula?
Thanks for posting your query.
Considering the details you have provided it does seem that your child is not having normal stools either due to a gastrointestinal infection or intolerance to the formula.
Its less likely to be intolerance since you mentioned that his bowel pattern was normal for 2-3 weeks after shifting to formula.
The next best step would be to get his stool routine and culture test done to confirm the diagnosis .Some infections might not cause diarrhoea for first several days and gradually change the stools if left untreated.
Even if its intolerance the test may indicate its severity and wether it needs any further treatment .
Depending on the report the child might need a course of antibiotic and probiotic supplements to aid his digestion.
Once the cause is treated his gassiness and other symptoms should resolve within a week or two of starting treatment .
So please do not worry, but do not wait further and do consult his pediatrician with the reports.
Hope that answers your query.
Wishing your child a speedy recovery.
