Riding a mini

Miniature horses are not meant to be ridden,they are cart horses, though many people don't know that... they can actually be hurt from being ridden. If it's a larger (over 40") mini maybe setting a small child on there for pictures or for a very short ride probably wouldn't hurt, but nothing over 30lbs. They are actually "built" different than any other riding ponies... I got my daughter ( who's 2 1/2 y.o.) a shetland and she rides him. He's 42" but he's stocky and she never rides him more than 10 minutes...
