Tell us about 23 days, we barely sleep but we don't cry either? Sucking on the breast like a desert, and only half-asleep eats. Who had this? Maybe lying down for a long time. At first there wasn't such thing, it appeared a couple of days ago. Maybe sucking like empty, but eating hungry, eats normally. I don't know what it is? In what return did you have a regime? We sometimes don't sleep during the day, sometimes at night.
