Dani wants to do whatever he wants, eat what he wants, and not take any notice of adults. Have you ever behaved badly? Do you want to learn the most important rules of good behaviour? A child has to learn to accept frustration and delay gratification. Children should share their toys and understand that games, mostly, need the participation of others. Nobody likes children who are selfish and dictatorial, but it is up to adults to show them the way to behave. We need to be an example and transmit the idea that "I" is not as important as "you" and "we".
