My little one is 2 weeks and 5 days old. On Friday she had a weight check appointment. She was born 6 pounds and 4 ounces and she is now 8 pounds! She gained a full pound and a half in a week!!! Also from day one she's been lifting her head all by herself. I was holding her in the burping position at her appointment and she was lifting her head and looking all around the office. The doctor saw her and she said she shouldn't be able to do that until she's atleast 2 months old. The doctor said she's really advanced and it made me feel great! Of course I still hold her head and support her but my little girl is doing so good!!!
