Between the ages of 12 months and three years toddlers begin to develop language and invariably struggle with expressing their wants and needs. Moreover, the part of the brain that is responsible for impulse control is just starting to develop. To help speed this process parents can encourage their children to link the feelings a child is physically expressing into words. In age appropriate language, explain the concepts of excellent and poor behavior, the rationale behind it, and the age appropriate consequences for their behaviors. And always affirm that regardless of the behavior he or she is still loved unconditionally.
With regards to consequences, time outs allow toddlers to calm down and regroup. Somewhere around the age of two years they are able to understand the concept and comply. One minute for each year of age is an appropriate amount of time. The key is to be consistent and use time outs for more extreme negative behavior (i.e. hurting another child).
