If you are in tune to your child you will be able to tell when he/she is ready to learn how to read. They have different ways of letting us know when the time comes.
1. Some of the kids learn the favorite books we read to them by heart and like to sit pretending to read them.
2.Some children ask us about words or letters. Whats that word say or whats that letter or how do you make that letter.
3.To see if the child is ready teach him/her to write or pronounce one or more sounds. Does he/she want to learn , seem interested in learning them? or does the child resist?
