Kids always look up to their parents as a role model or heroes and try to do or copy things done by their parents. But no parent is perfect either and sometimes their actions are inappropriate that their kids shouldn’t learn. Actions like spitting is a normal behaviour for adults but it is unacceptable behaviour from a child’s perspective.
There has been observations where kids are seen spitting. There could be many reasons to it like they spit just for fun, to grab attention, express feelings or maybe show authority but there is a possibility that they have learned it from their parents. So parents or adults in general need to watch out for their actions and teach their kids why it is abysmal to spit and reinforce good behaviour.
