First let me express my new found deep love for this program! It is a true blessing and I am so thankful for it, it's creators, and for the wonderful support found here. I cannot tell you how blessed I feel!
Now, I do have a concern....I am using LHFHG for my DS 6 and using all the kindergarten materials except for Thinking Skills which he can do quite well. I figured this is our first official school year so we're taking it easy and really trying to enjoy the journey (which isn't hard to do at all!!) I also am using LHTH for my DD 4 mainly for her letter & sounds learning. The "problem", if you want to call it that, is that she is right in there with DS doing all the LHFHG activities except for any written work (no handwriting, written math, or thinking skills type stuff). And she's doing WELL with it. I know you can make these programs as flexible as you want or need them to be but if she cruises along with DS in LHFHG at age 4 what in the world do I do with her next??? I really don't see her being able to go into Beyond at 5 years old (stranger things have happened I suppose but....). And there's no way to 1/2 speed her. She's too insistant on being included in everything! Basically, I've been doing LHFHG with both and then supplementing with LHTH for her to do letters and craft things. I just don't know what to do with her next year. Help?!
). So, this all brings me full circle to the start of this post, back to saying you really will know better after you've finished out LHTH and LHFHG! 
) And Reddy Fox is a HUGE hit! I hope she will continue to enjoy it this much next year.
