My 15 day old baby is on breastmilk and formula milk. His stools have been watery and yellow, and does not seem normal. Everytime I feed him breastmilk, his stomach makes gassy noises. I have tried hing on navel, tried jayfal gutti, have given gas medicines too, but no improvement. I am on very simple diet myself with no food which can cause gas, then why is my baby getting so much gas?

I think you should ask your pediatrician. Be cause if your breast milk is enough you do not need to give formula. May be you need to change your formula.
