LeAnna,
Sorry I've taken a bit to get to your post!

We've just gotten all the book packages for the new book off to our website designer, so my time on the board has been cut lately.
I view LHTH as a kindergarten readiness program. If you add phonics, handwriting, K math, and reading out loud of good books, it could be a kindergarten program. The best way to determine which program your little one should use is by using the placement chart linked here:

If your child clearly places in LHFHG, then I wouldn't drop back to LHTH. However, if your child clearly places in LHTH, then even if your child is 5, I would use LHTH. Does that make sense?
If your child is already doing phonics, handwriting, and math, then it is pretty likely that your child would also be ready for LHFHG even at half-speed. However, if your little one has never covered all of the "readiness type skills" that a kindergartner should have prior to kindergarten, then LHTH would be the better fit. With those who are just turning 5 it is always a judgment call by the parent as to what is best program-wise.
If you get a chance to pop back in, I''d love to hear more of your thoughts after you look over the placement chart.
dale1088,
From what you've shared about your 5 year old, I'd agree that he would fit best in LHTH. It will firm up his basic skills heading into Kindergarten (i.e. letters, letter sounds, numbers, etc.).
Blessings,
