#AskTheExpert Hi. the baby is 5 and a half months old and doesn't sleep at night. Over all, his sleep is always unsound- day or night naps. (He had really bad gas problem which has reduced very much since birth.) I am struggling to make him sleep at night and have tried everything- warm baths, play with him for 3-4 hours before bed time at night, giving him colic-aid as prescribed, but none is helping. Really need some help regarding this.
