grandson needs a gentle ride

Additional Comments:
wanted shorter horse well broke for a 4 yr old. ponies okay, anything around 14 h or shorter. our grandson is riding my 16 hand horse and that scares me a bit. she is way too tall and if he falls would be a scary moment for me. looking for a good ride for this little feller. he wants to be a cow man when he grows up and we sure would like to teach him the ropes. call or email what ya got... thanks, wayne
