Hello Doc, My name is Shuba and I have a 2 month old daughter. I feed her Nan 1 around 90ml, 3 scoops 4 times a day as my milk is insufficient. She passes stools normally 3 - 4 times in a day. I also breast feed her every 2-3 hours. The problem occurs at night. She cries a lot and makes some loud grunting noises as though she is applying lot of pressure to pass stools and has some uneasiness in her stomach. This goes on for 1-2 hours. Once she passes her stool she stops crying. During the day she is normal, only at night this problem occurs. When I try to feed her during this time she has 2-3 sips and cries again. I wanted to ask u if this is normal behavior, also if I can give her Aristozyme drops and what dosage? Is she having stomach pain? I also tried giving her drops for infant colic called colicaid but it did not help.
