My daughter had her for doctor's appointment today. Her doctor was very impressed by her. She's gained 3oz in 3 days! I've been pumping and nursing her. I pumped before the appointment almost 4oz, I pulled it out because my daughter was hungry and she finished the whole thing! her doctor was surprised by how much I was able to produce in such a short time. She mentioned that she's due in September and wanted to know my secret! 😊
