I have a 6 year old step daughter, and she LOVES our ball. He seems to enjoy being handled by her (likes to get in her hair!) and is quite tolerant. He's never been aggressive toward her in any way despite the occasional accidental poke in the face she's given him. (oops)
Her mom, however, HATES that we have the ball. Not for safety reasons, but simply because to her it's "weird" to have a snake as a pet and she doesn't want us making her daughter "weird" like us. I could totally see her making up some stupid safety reason as an excuse to control our home.
She did the same thing with our cats - claimed for months that Stepdaughter is allergic to them (she's not) because the mom hates cats, too.
