I don't know, it seems pets follow the same pattern of behaviour, very 
lively and foolish at the beginning, then settling down gradually. It's 
not that they cannot move around and play anymore, just that they do it 
less often. I don't think it's just us imposing that on them, for 
example cats do that yet they take little heed of our orders ;-) I 
wouldn't be surprised if wild animals did that too.

I think there are other things that might explain the activity of 
youngsters. For one thing, they are growing physically, so maybe the 
body needs this movement to form properly. The brain is also developing 
at this age, and possibly it needs as many stimuli as possible...
