You might try something that has music to it with blends. I used Hooked on Phonic & Abeka with Vicki. If you can find a tape or cd with blends of letters you can make it game and sing it. Singing always works with Vicki. Just trying to help.
2 Timothy 1:7
For God hath not given us the spirit of of fear, but of power, and of love, and of a sound mind.
