Are babies 1 years going through a growing period when they start to sleep more?

The programme is narrated by David Jason and presented by Nigel Marven. The fictional component is the theme that Nigel goes back to various geological time periods through a time portal, and brings back live specimens of extinct animals back to the present day, where they are exhibited in a wildlife park named Prehistoric Park, which is a big area between high steep mountains and ocean (which serve to help confine any escapes) with varied environments.
