I do all the things in the HOD guides with my kids as we're doing school. (And we LOVE the amount of Bible content that is there!

It's not just in the Bible box but saturated.) Our family does have a family devotion time, as my husband has a desire to do that with the kids. When we only had Grant and he was young, we read through story Bibles. Now that he's older, our favorites have been Our 24 Family Ways and the book we're currently using, Parenting With Scripture. I don't know that the last one is really designed to be a family devotional, but it's full of topics and then it gives Scripture that addresses those things. So, my husband is using it as a springboard to look up some of the different verses on the topic and talk about them with the kids. It has MANY things...like Cheerfulness, Anger, Friendship, Obedience, Complaining... I know that it's probably meant more for you as a parent to use as a reference for when you're seeing character issues in your kids so you can point them to God's Word and see what He has to say about how they're acting. But it's working well to use as a family at breakfast, too.
One other idea I had after doing Bigger Hearts with Grant, was to sing with the kids during our devotion time. In Bigger, you learn hymns. Grant loved singing them (and the little ones - then 3 and 1 joined in, too.

). Anyway, at that time I was putting together the music for church, so I occasionally sang the songs we were going to use in the worship time Sunday with them, and then they could participate better in church because they were familiar with the words and tune of the songs. I've been thinking that I should see if I can get the lists for the Sundays I'm not the pianist (as I'm not choosing the music right now) so that we can sing during the week again. Just another idea...
You'll have a great time with LHFHG with your boys! We're thoroughly enjoying it here (and are eager to do the second half when we start up again.
