My newborn

Drew

My daughter was born on 12/27/18 her birth weight was 8lbs 4 oz when we left the hospital she was 7lbs 15 oz and she had a weight check two days later and she was 7lbs 11oz and today at her one week she is 7lbs 8oz and the doctor is concerned with how she isn’t gaining weight and just keeps losing weight she eats 2 oz has normal amount of wet and dirty diapers. But sometimes we have to wake her for feeding every two hours. Has anyone else had this problem?? Also anyone else one week old eat more then 2oz?? My doctor says not to feed her anymore then 2 oz but sometimes she doesn’t seem happy with just 2
