When parents say, "I'm training my child to use the toilet," what they really mean is, "I'm training myself to remind my child to use the toilet." Unfortunately, this often turns into a power struggle, with parents saying, "You will," and children saying, "I won't. You can't make me." Parents use all kinds of tricks to win the potty training battle: treats, pleading, lectures, threats, and even punishment.
Although children naturally want to do what "big" people do, not every child is ready for potty training at the same time. Moreover, if parents push too early, training is likely to backfire, producing unwanted behaviors. Some children use it to get undue attention from their parents. Some turn it into a battleground to prove who is boss. Less assertive children can develop a sense of self-doubt or shame.
