Great riddle

[Denmark]

Heres one you probably know but here goes

What walks on 4 legs as a small child,
walks on 2 in its prime,
And walks on 3 in it old age?

if you say "as a small child" and "in it [sic] old age" that gives it away. It's 4 legs in the morning, 2 legs in the afternoon, and 3 legs at night.

also it's a bear.
