A no-neck-monsters behavior in public tells me a book load of information about the lack of/laziness of parental discipline and a total lack of respect for others.
There is a fine line between discipline and abuse when it comes to dealing with certain types of children. Bad behaviour in a child does not always equal bad parenting. My child was diagnosed with “oppositional defiance disorder.” Nope never heard of it before either, but we couldn’t even get her to go in a 5 minute timeout in her room, One time at the age of 8, my husband attempted to physically hold her there and she yelled and kicked at him. She would get violent. Would you have had him get violent back? Fortunately, she behaved pretty well when out in public though....just lucky there I guess. Wouldn’t want people thinking I didn’t respect them.
