Subject: Strep throat vs. Hand foot and mouth disease

My friends's baby got a case of hand foot and mouth disease, which subsequently
gave her Strepp throat. later we found out online it is the adult manifestation
of Hand foot and mouth.  my question is- why does the disease manifest
differently in babies? and why does it result in sores on the feet and hands? we
thought that perhaps it was the babies lack of immunities allowing the virus to
penetrate the skin more easily, but have no idea if this is the case.  can you
help us figure it out?
