My baby is 2+ months old and he is having quite fould smelling green,sticky stool after I started feeding Nan pro1 formula.Also he vomits a lot. he is both breastfed and bottlefed and he poops once in a day.previously i used to give him cow milk with 3:1 ratio water and milk,but he was facing constipation but the stool was yellow. I am concerned about the greenish colored poop - is it normal or does that indicate something is wrong? Please advice.
Formula feeds like NAN Pro 1 are cow milk based and hence difficult for the child to digest and hence the child may vomit or there may be changes in stool. Diluting the cow milk is better than giving in undiluted form. There is no substitute for mothers milk. A child of this age may pass stool once in 10 days or 10 times a day and both are normal. Unless stool is hard, it is not constipation, and you need not worry. Green stool is normal in child Chat Doctor.  If possible switch back to breast milk. You may also give expressed breast milk.
