Thank you for your query on Healthcare Magic,
Breast feeding is the best for baby as it wont have any problems associated with feeding.
For gas problem
, and stool color change, no need to change the formula and frequent change of formula will lead to confusion regarding the tolerance of feeds by infant.
Don't give cow's milk as it is associated with indigestion
due to presence of large molecule proteins
and cow milk protein allergy
Don't worry about stool color and frequency , continue NAN 1 as advised.
Gas problem is common in 3 month old and it can be managed by giving neopeptine
drops with your doctor prescription.
Passing stool once in a day is also normal.
I advise you to continue Nan 1 and if you have any clarification please let me know.
Hope I have answered your query.
