Try this sometime.
Get a group of children
in a room with a light fixture
hanging just out of their grasp.
Then watch what happens:
one child will jump to touch it,
and before you know it,
every kid in the room will be leaping like Michael Jordan.
They're testing their skill,
stimulated by the challenge of reaching something
beyond their normal grasp.
Put the same children in a room
where everything is easily in reach,
and there will be
no jumping,
no competition,
no challenges.
The problem with American education
is a low ceiling of expectations.
We have built schools that demand and teach too little,
and the children have stopped jumping.
- Carroll Campbell

Children need to be challenged by the home as well as by the home.

Children who are raised as bilinguals have the advantage of increased input from their home. This attention is an additional and significant benefit of bilingualism. They are challenged by the need to learn two (or more) languages at the same time, and they usually rise to the occasion by showing that they can, indeed, speak both languages as successful as other children speak only one.

Children create their own challenges. They race each other, they play games in order to win, they try to be the first in any line, they try to outwit their elders. They need challenges in order to determine and understand their own limits.

Don't feel sorry for your children by shielding or protecting them from challenges. They do not want or need that favor. They are looking up to you to help them determine their own limits. Help them by offering them the challenges that they crave.
