why my daughter do not sleep at night her age 3 months 10 days

USUALLY THE SLEEP DISTURBANCE IN YOUNG AGE MAINLY DUE TO COLIC AND THIS COLIC IS ONE OF THE NATURAL DEVELOPMENT IN CHILREN BUT IT CAN BE MORE PROMINENT IN BABIES WITH FAMILY HISTORY OF IRRITABLE BOWEL SYNDROME OR ALLERGY
THE BEST TREATMENT IS BURBING THE BABY PROPERLY AFTER EACH FEEDING AND IF THE BABY ON BREAST FEEDING ,HIS MUM SHOULD AVOID HEAVY MEALS AND CONSUMPTION OF LARGE AMOUNT OF MILK
DRUGS SOME TIMES MIGHT HELP BUT YOU SHOULD USE IT AFTER CONSULTING YOUR DOCTOR
