While the young boy appears to be enjoying himself, some have said the parents are exploiting their child and putting him in danger.
"So dangerous and stupid," one person wrote.
Another said: "He looks scared and unsure."
But Casey and Mindi say they've got their son's best interests at heart, explaining he is developing faster than other children.

They explained there's a lot of preparation and safety that goes into Rich's water-skiing and they would "never put him in harm's way".
Others supported the couple and baby Rich, with one saying "I don't think it's child abuse if the baby loves it, which he clearly does!"
