I'm a terrible babysitter

My SO decides to leave me at home with his nieces & nephews (it's 5 of them here) ages 2-8 so I just finished eating & they see me taking my vitamins & they start to beg me to let them take one. I told them if they take one a baby will grow inside of them so now all of them rolling on the floor crying cause they don't want to have babies. But none of them actually took one so I'm just sitting back laughing, yes I know I'm terrible!!!! 😹😹😹
