It is essential to encourage toddlers and preschoolers to speak as soon as possible. Alphabet activities is a good start.
I remember learning the alphabet at about five years old. I was slow in learning to read because I developed a lasting fear of reading aloud in class. I only remember the awful anxious pit of worry in my stomach as my turn came closer and closer. I avoided speaking up in grade school classes and that fear followed me through high school. A sorry state to be in when it is time to decide for college or a career.
A preschooler can have fun with the alphabet with the VTech Alphabet Apple game. Early learning builds confidence and courage too, because when something is learned the child feels they are good at something. Parent and child have time for eye contact and vocal interactions. Much needed skills for entering school.
