we used headsprout with my dd when she was 6. my ds also uses it currently & he's 5. he's only on episode 13 & we started in early september, but he rotates with bob books, hooked on phonics, & reading eggs (we have a free 6 week subscription there currently as well). anyway - headsprout is very good imho. when my dd used it, she didn't really like it so much, but i can honestly say her reading began to click after using it. my ds actually really likes it a lot though & is already reading small books. it's $199 for the full 80 episodes, but i found it half off with a coupon code. my son also loves readingeggs.com, but headsprout is probably better suited for your children's ages. hth.
