Sandpat,
That's actually one of my favorite verses! Though it's for a little boy, he won't be little for long, and this verse contains wonderful advice for his future. It's not what we'd think of as a kid's verse, admittedly.
Were it me doing the verse, I'd do it thus:
Proverbs 3:5-6
Trust in the LORD with all thine heart; and lean not unto thine own understanding.
In all thy ways acknowledge him, and he shall direct thy paths.
If you just leave a bit of space between the verses, the reader will get the idea.
