Girls, hello everyone. I gave birth on August 3rd, it was cesarean section. The baby just barely took a sip of water. We were lying in the maternity ward before today. Today we're being transferred to the children's department. Apparently for an examination. I asked the doctor why, she says that he drank some water and that he's eco (meaning "low birth weight"). They say we need an examination. Has anyone had this experience?
