My almost 5 month old daughter is waking up every hour at night for the past 3 days. She cries and wakes up and when I try to feed her, she will sleep in my arms within 2-3 mins and not take any more feed. Earlier she used to sleep for 3-4 hours between feeds. I am not sure what’s the reason of waking up if it’s hunger or something else. What should I do?
