My daughter was born at 35w2d so she was premature weighing 4lbs2ounces. She was discharged from NICU 2 days ago and the nurse said to feed her on demand. Since she's been home, during the day she would wake up every 2 hours to eat. Then at night, I would wake her up to eat. My question is, now that she is back to her birth weight, should I wake her up in the middle of the night or should I just let her wake up to let me know when she's hungry?
