Hi Renee!

Your ds could do LHTH or LHFHG next year. LHTH takes about 25-30 minutes to do each day, and will have him focusing on these things:
Daily: letter recognition, letter formation, letter sounds and motions, finger plays, music,
One Time a Week: early math skills, Bible activities, devotional topics, art projects, dramatic plays, active exploration
Here is the first week of plans so you can see what he would be doing each day (you do 1 page of plans each day):

Here is the LHTH Photobook so you can have a visual way to see what he'd be doing...

LHFHG takes about 1 1/2 hours to do each day, and will have him focusing on these things:
Daily: Bible Memory Work, Rhymes, Gross Motor Skills, Music, Fine Motor Skills/Handwriting of Letters, Phonics, Storytime, Language Activities, Math Exploration
One Time a Week: Devotional Topics, Dramatic Play, Thinking Games, Art Projects
Here is the first week of plans so you can see what he would be doing each day (you do 2 pages of plans each day):

The placement chart will also help you decide what would be best for your ds...

I am thinking you have several good options here.
Option #1: You could do LHTH with the Ages 4/5 resources.
Option #2: You could do LHTH with the Ages 4/5 resources and add in the right side of LHFHG for LA/Math.
Option #3: You could do LHFHG half-speed, doing daily phonics though, and going to full-speed when you think he's ready.
Option #4: You could do LHFHG full-speed with the K options 4 days a week.
Option #5: You could do LHFHG full-speed with the K options 5 days a week.
After you get a chance to look through the placement chart and the links, I'd love to hear your thoughts and chat some more! HTH - we have loved HOD so much - I think you'll find it easy to do 2 HOD guides at once, provided dc are placed correctly. We have found this to be such a terrific way to homeschool!
In Christ,
