That’s a fairly effective way to teach a child not to bite, however, he bit the child hard enough to leave marks and he bit him at least 7 times all over the body?
This guy needs to be jailed for stupidity if nothing else, he is a danger to childen.
I really doubt this is ever an effective way to teach a child not to bite. And at least one of these bites was on the 2 year old's genitals. This guy needs a permanent home in a secure psych hospital.
