We began getting familiar with the letters of the alphabet when my daughter was 2 (she is now 3). And that is exactly what it is-getting familiar!!!! In my opinion there is no right or wrong time to introduce literacy to children, the earlier the better! While they may not recite the letters, or even associate upper case letters with lower case letters, the idea is to let the visual opportuniy be available to them. That way they will start becoming familiar with the formation of the letters and with the sound and pronounciation too, thereby paving the way for reading later on.
When we do our activities I say the letter and I do the sound a few times. I like her to repeat after me, but even if she doesnt its ok. When we move on to the next letter, we revise the old ones that are up on our wall. Id like to again add that even if she doesnt repeat it, I am quite satisfied that she is receiving the visual and oral stimuli.
I have introduced mixed media to my little one, it provides the sensory stimulation, I allow her to get messy and feel and experience each items unique attributes. We are using poster paints, acrylic pva, finger paints, do-a-dot paints, watercolours, oil pastels, wax crayons, glitter, stickers, appliques and embelishments, stamp markers and much much more as we go along.
