Praise is in fact a powerful medicine, particularly for children.
Parents praise their children naturally. At first your child needs more words of praise, sincere praise for ordinary behaviors. It isn't long before he needs considerably less praise, since we're attempting to prepare the child for a world in which praise is not given repeatedly for all things that are praise worthy, but one that looks upon too frequent praise as insincere. Pats on the back don't occur all that often. Once praise has taught a child to take his own worth for granted, energy need not be wasted on thoughts and feelings of self-doubt, but can be used to work toward productive goals.
