Many psychologists argue that ages 3-5 are some of the most critical years in a individual's development. This is when children discover their independence and sometimes rely on temper tantrums to get what they want, and what the word "NO" really means. As a direct result, this age is often difficult on parents.

Questions regrading children and formal education arise. Knowing when to introduce a child into preschool is extremely important.

Graduating from diapers to spiderman underwear can also be trying. Locking your youngster in the bathroom until they have no choice but to use the toilet is never in the best interest of the child.

Language is another qualitative change. A child's 3 word vocabulary develops in to a massive 10,000 words in a very short time. "Mama" at age 2 will become "Mom, may I please have a glass of water" at age 4.

It is important that parents learn their child's boundaries during this developing life period. Parents must set guidelines for their child, yet they must also allow the child to grow at their own pace. After all, children are developing people, and they do not always progress or digress at the same rate.
