The girls I have already depression. The baby is 5 months premature (born at 30 weeks and 6 days). About 1-2 weeks ago he started taking only breast milk while sleeping. And when he's awake very rarely asks for a feed, but when he's attached or sucking for just a minute and cries, or he doesn't take it at all and cries. He cries very much. He poops every day or every other day.
