I can see my 4 year old easily fitting into LHTH, that's a no-brainer, and he would easily move into LHFHG next year when he turns 5.
My older two boys are not so easy to fit.
We have been homeschooling for 2 years already, nothing too heavy, just 4Rs, nature study and whatever interests them. They are both reading very well. DS1 can read anything you put in front of him, DS2 has discovered Magic Treehouse Books, and has nearly completed Abeka K5 Phonics. Both started Abeka K5 cursive this year, which I have found very successful. They can write words and do small amounts of copywork (lists of planets, animals, short excerpts from their favourite picture books), and will do their own writing on a very small scale (signs, cards, very short letters) depending on their interest. Their maths ability is also extremely good. We're doing Abeka 1 Arithmetic and, again, we are in a good rhythms and are doing very well with it.
I've looked at all the charts for placement and as far as skills are concerned they seem to fit in with BLHFHG and BHFHG for language arts and I am very relieved to find something that's so beautifully straightforward (thank you, thank you, thank you!). DS1 could do DITHOR and DS2 would handle the emerging readers. However, and this is where it gets complicated, we're in Australia and the US history compenet isn't as culturally relevant. I love American history and have a college major in it, but it's not quite what I want to begin with my boys. I really like the look of PLHFHG because of the world history aspect (we have Hillyer's book and have read and enjoyed bits of it), but I don't think they're quite mature enough for it yet. DS1 might be, particularly if the interest is there, and DS2 will tag along because he HAS to keep up

So, I can see my options being as follows:
1. Do LHFHG history with BLHFHG or BHFHG Basics, followed by BLHFHG history and BHFHG history. (We'll be using them for the younger two anyway).
2. Do PLHFHG history, keep doing our own language arts and maths programs and add DITHOR, and take a little longer to do it.
Sorry this is so long, but I'd really appreciate any suggestions. The less tweaking I have to do, the better. I've looked at nearly every curriculum under the sun (Sonlight, Ambleside, Living Books, Abeka, Rod & Staff, Horizons the list goes on
