Are kids meaner to moms?

Is there a difference between mom vs dad voice? Haha

There's a scientific study that i watched on facebook that the kids react 80 to 90 percent worse when theyre with the mom compared to when theyre with the dad or any other caretaker

My ex partner always told me that my voice is too nice you have to sound more commanding haha so i try to put on my scariest strictest mom look then he just looks at me then looks away and pretend nothing happens

But when his dad tells him something like by simply calling his name he's like yes dad? Like what the heck? Haha

My ex partner say its with the tone of his voice haha he is not even raising his voice but you will see that the kids is scared already haha

I guess its because and i think that kids behave worse when they're with their moms cause they find security in us. we are their safe zone.

How about your kids?
