Solid and Liquid Snake were born in 1972, with Solidus being born at some point between then and the Les Enfants Terrible project's shutdown in 1976. Peace Walker takes place in 1974. If Chico were a product of the project, he would be two years old when we first meet him. Either Les Enfants Terrible occured significantly before everyone thinks it did, or Chico's accelerated aging kicked in very early, progressed very rapidly, and then presumably slows way down again so that he doesn't look a million years old by the time we see him again in the 2000s.
