My baby is 4 month old and as he rolling due to pressure on stomach he is vomiting a lot and his toilet is yellowish color proper but doing 3 to 4 times a day little little. Here he is drinking and then rolling and then vomiting. He is not vomiting milk but it's like dahi. Dr. he suggested perinorm 8 drops thrice a day is it safe to give him perinorm as I have read a lot of side effect of perinorm. If not safe then kindly suggest me the substitute for d same.
