Sir I recently delivered boy now 3 and half month. Giving breast feeding. Some times bottle feeding. He dnt have major problems. Sometimes he will shake leg slightly and I went for checkup and doctor did cbc and calcium was showing 8.1. Calcium levels are low. And one thing I need suggestion how much wbc count is normal for 4 months baby? For my son 16500 is there but no infection and no fever. Doc said variation is there in infants. Am in panic. Please suggest me how much wbc and platelet count is normal in babies.
