The soles of normal babies’ feet are usually redder. Because the skin on the soles of the baby’s feet is not as thick as that of the adult’s stratum corneum and is rich in capillaries, it can also appear red. If you find that the soles of your baby’s feet are very white and have no blood color, in addition, look at your baby’s lips to see if there is any pallor, and your baby’s fingernails to see if there is any pallor. If these places are pale, you need to go to the hospital for examination, so that the doctor can see whether there is the possibility of anemia, and whether you need to test the blood routine. If the hematocrit is low after the routine blood test, it suggests anemia. If anemia occurs, the first thing to do is to pay attention to the intake of iron in the diet, such as eating more red meat (pork, beef and mutton). If the degree of anemia has reached moderate to severe, oral iron is needed to treat, the effect of dietary therapy alone may not be so good.
