Julie posted a reply to my dilemma, that actually made me gasp. I'm only posting here in a new thread, because I know she is busy and was hoping you ladies could help me. She suggested that maybe I do them separately. I could do LHTH with my twins, and then LHFHG with my 7 yr old.
Fear and panic swiftly rushed through my veins.

LHFHG will take about 2 hours to complete. I'm not sure I can get my son to focus for 2 hours straight. There is a possibility though. I see him improving everyday. He is severely dyslexic, so the phonics portion of our day is very mentally draining for him and he needs a break after that.
While I'm doing LHFHG, what are my 5 yr old twins doing? Playing? Running a muck?

Lastly, my twins place right in the middle of LHFHG and LHTH. I have the LHTH guide, and I had all intentions of doing it with them, but at that time when they were ready, we were still trying to figure out what was causing my son so much difficulty and how to get him going. Now we have that figured out. Do you think I could do LHTH with extensions? My twins know most of the letters and sounds, and because dyslexia is so prevalent in our family, I work on some special things with them while they are learning the letters and sounds. They are doing Earlybird Math 1(the new book that combines 1A/1B) and working through a handwriting program. Do you think it would work if I did everything in LHTH, but left out the Finger Play/Letter Activity/Math Activity?
Thanks,
Tracy
