My daughter had a weight check today. She now weighs 5 pounds 10 ounces and she's 10 days old. When she was born she was 5 pounds 9 ounces. 3 days later she weighed 5 pounds 6 ounces. The doctor wants me to feed her 2 ounces every 2 hours. Problem is my daughter never ate that much. But I gave it a try but she spit it up. this is so stressful!
