My baby cry a lot continuous at evening or late night. Doctor says the problem is off colic pain and gas. We are giving our baby medicines gastica neopeptine promethazine syrup normetrogyl .my baby is 2 month 18 days old. My question is these medicines are safe as these medicines solve the issue for few hours we want a permanent solution or recommend a medicine which can be given once in a day so that my baby feel relaxed. We have also changed his milk from farex to nestle lactogen now my baby cry less but his toilet color is grey other than yellow . mothers feeding is also less due to insuffient milk output. I am very confused how to resolve the problem . what is right and what is wrong. ...plz tell me the solution.....
