Ladies,
I know it can be interesting to know how to handle your little ones preschool years, and I understand that there are many preschool and kindergarten programs out there than you can consider using.

For the purposes of the HOD Board, we do try not to spend time talking about products not related to HOD. So, from our perspective, you can explore several options as far as HOD goes.
You can ponder stretching LHTH out over 2 years doing it 3 times a week. You could do LHTH half-speed over a year and then go full-speed the following year 4 days a week. Both of these options will stretch LHTH out over 2 years.
If you happen to have a child who is older but is not quite ready for LHFHG, you could instead do LHTH at full-speed and add in any of the 3R's from LHFHG that your little one seems ready to tackle.

This could mean doing the Rod and Staff workbooks, the handwriting K, the phonics, and possibly even the K math. You could actually pick and choose which of the 3R's your child seems ready to add.
Then, the following year, you could just head into LHFHG and pick the correct level of K and 1st grade options for the 3R's to meet your child's needs.
Another option is to do LHFHG over 2 years. This can be as easy as doing the left side of LHFHG one day and the right side the next for a season.

Then, the following year, you'd be ready for full-speed 4-5 days a week.
With any combination of these options, you'll often find that your kiddos will arrive at full-speed eventually and do very well.

I honestly did a myriad of programs with my oldest son during his preschool years, so I know what you are pondering.
But with my next 3 boys, I've only done the HOD route, in many of the different scenarios that I've outlined above, and we've found it to work very well and be very good preparation for the regular HOD path.
You'll know best what route will work well for your kiddos, and I fully realize you may choose to deviate from the HOD path. I just wanted to pop-on and give you some HOD scenarios to ponder rather than sending you somewhere else.
Blessings,
Carrie
