Many parents even teachers have a hard time finding ways to let their child know the alphabet.For me as a mom, as a teacher, I am always concern of the child's balance life.My son was late in his reading development.He loved numbers during his formative years.This strategy that I have been using to my two children is quite effective.This exclude my third one because she is not ready yet,I never force the child.Reading is developmental.Time will come they really need to be ready especially when it's time for them to go to School. My mom always tell me that the best way to let the child learn about something is through repetition method.
Since then,I am doing that method to my children.First,you say the letter and let the child say it after you.After you said the letter you also need to say the sound of the letter, and let your child say the sound too after you.Never forget to say the sound of the letter because it's the sound of the letter that you will use in the reading process not the letter recognition.One time, I remember my daughter,she forgot the letter,but she remembered the sound of the letter, which is more important.
Then you need to apply the repetition method.Do the same thing: say the letter and let the child repeat after you, and say the sound of the letter and let the child repeat after you, " everyday".In a month or so, your child will be able to recognize all alphabet.
Remember, repetition is the key.As simple as that!
