DD was born at 36 weeks. She was a good size (3450 gms) but her sucking reflex wasn't great. She was very sleepy too. We were discharged five days after she was born but she was readmitted to special care two days later due to jaundice. She spent a couple of days under lights and was fine. When home she slept right through from the first night, I had to set the alarm to wake her up to feed.
