Newborns usually have cold hands and feet soles because their circulatory system
is still under development. Maximum blood flow occurs to vital organs of the
body. Hence their hands and feet soles remain cold. As the babies grow, they
tend to move more and become active; this is when their blood circulation also
improves a lot. As the blood circulation improves, their hands and feet soles
have a similar temperature like the rest of the body. For infants, make them
wear socks and keep them covered properly. The temperature of the baby's chest,
hands and feet soles should be the same.
