When is a child with DS ready to learn phonics?

[Guest guest]

Just a question for some of you homeschooling and school moms:

How do you know when your child is ready to learn phonics? I put the

following seven flashcards out for :_ap, _at, _ag, _ad, _ab,

_am, and _an. He doesn't seem to get the concept yet of substituting

the difference beginning sounds, he is so used to sight words. Do I

need to pursue this daily or just wait? He's been able to read sight

words for a long time. I don't know if he's not ready, or what. He

talks a lot, just the other day as we were driving in town, he said " I

want a blue cake with frosting on it, and I want to eat the whole

time " . As I drove past the store, he said " You missed it " and " Turn

around " . is 10 years old.
