My baby is 1.7 months old and she is waking up middle of the night suddenly crying a lot from past 3-4 days. What must be the reason for it? I have also tried to feed her during that time still she won't stop crying. It continues from 10-15 min to it sustains some night for around 2-3 hours.. She calms down for few minutes and again start running but will not sleep again. Past 3-4 days both of us are unable to sleep properly at night. What shall we do in such situation. We are helpless as we don't know what she wants and why she is crying so badly. It is happening from past 3-4 days only.
