Author's note: here is some info on sickle cell just for a little help for those that don't know about it these are the symptoms( for more info please visit - http://www.mayoclinic.org/diseases-conditions/sickle-cell-anemia/basics/symptoms/con-20019348 ):

Signs and symptoms of sickle cell anemia often don't appear until an infant is at least 4 months old and may include:

Anemia. Sickle cells are fragile. They break apart easily and die, leaving you without a good supply of red blood cells. Red blood cells usually live for about 120 days before they die and need to be replaced. But sickle cells die after an average of less than 20 days. This results in a lasting shortage of red blood cells (anemia). Without enough red blood cells in circulation, your body can't get the oxygen it needs to feel energized. That's why anemia causes fatigue.
Episodes of pain.
Hand-foot syndrome.
Frequent infections.
Delayed growth.
Vision problems.
