laws that punish parents for their little children's actions against the laws get parents worried
这里理解的 时候断句是
(laws) that punish parents(for)thier little chidrens actions against the laws(get) parents worried
还是 laws that.... get ....
就是说 那for 后面的 短语 是 什么成分
理解的时候该理解成the laws ..for 还是 理解成that 从句的一部分
laws get parents worried 什么样的laws呢，用了that告诉你，就是pupunish parents for their little children's actions against the laws 中文是说，由于小孩违反法律的行为而惩罚父母的法律让很多家长很忧虑for在这里感觉是由于，因为这样的意思
这句话的主句是laws get parents worried。这里的laws是句首那个而that punish parents for their little children's actions against the laws 是定语从句修饰第一个laws这句话的意思是：因孩子违法而处罚家长的法律使家长们很担心
