My kids at home use to have "kulitan" to the point that they already hit each other . One time I scolded them because of that and even spank there butts . Is it okay to discipline them like what i did or I'm doing it the wrong way ?

Corporal punishment are not a good thing nowadays. Parents advise to ha have a time in and time out instead. If they've done something wrong, you just tell them your time out or you just stay for several minutes and you're not allowed to play.
