Hello everyone. My daughter has been like this for almost a month now, and it's been three days of bad sleep. We're breastfeeding. She doesn't sleep all night, she eats, seems like only then will she fall asleep again, and wakes up and eats again. During the day she sleeps for an hour, eats, and then sleeps for another hour. I don't eat anything extra, mostly milk, soups, dairy porridge, oils, cheeses. I thought maybe she isn't eating enough. Has anyone had this experience? How did you cope with it?
