Dear Mridula,
Your child's hemoglobin is dropping too low before transfusions. Please transfuse your child when the hemoglobin is close to 10. Allowing hemoglobin to drop so low is bad for her bones, her spleen, he ability to grow and thrive, and her general well being. Appetite tends to be suppressed when hemoglobin is low.
Wishing you the best,
Sharmin
