My baby is 6 weeks old today and ebf. Things seemed to be setting down: she was sleeping more at night and having some good naps in the day. It was by no means perfect- she feeds very often and wasnt sleeping through or anything but we were getting by. But the last few days she has been crying a lot, and been sick much more often. Sometimes quite big amounts. Sleep has been more erratic, especially at night. I am not sure whether this is normal baby stuff or whether I should see a doctor. She'd hardly been sick until a couple of days ago. Just not sure what to do?.
