My 6 month old daughter has been waking up multiple times at night for the past 8-10 days. She is fed mother's milk. She wakes up every 25-30 min at night and sleeps the moment she is taken in lap and fed. Not sure what the concern is. Is it because she feels hungry at night and now needs outside milk and other food items? If yes then please advise what and in how much quantity? If no then what can be the cause of concern? She is all playful during the day.
