Hey Ken,
Sounds like you may have solved the issue, but if not we purchased bows for both our kids from Mike at Maddog Traditional Archery. He makes the bows custom in the same design as his adult version, but to fit your kid...completely custom. Each one was $100, but this is NOT a plastic toy bow...My daughter is 6 and has been shooting hers for 3 years now and still prefers it over any of her others (Mathews Genesis and another custom longbow made by some super guys, but she hasn't grown into it yet...). My son is 4 and has only had his for a few months, but he loves it. Great bow to learn with and stay with.
