Naughty 101

So. I have a 2 and 3 year old. both boys. currently they go to their dads 7 hours away every 2 weeks. so 2 weeks with me and 2 weeks with him

over the last few visits to dads. they have come home being awful. hitting. screaming. kicking. biting. fighting with each other. yelling mine. spitting in each others faces and laughing about it. back talking and telling me no.

on more than one occasion they have told me that dads girlfriend (we will call her PCB- Psycho crazy b****) spanks them. I flat out told pcb she better not lay a hand on my kids ever. their dad will not talk to me without her nosey ass listening in. she calls the shots. I cannot stand this wench.

she has began telling my kids she is their mom. not cool.

what can I do to make my kids listen and behave?

time outs aren't working. I don't like hitting my kids . I have lightly spanked them but it doesn't phase them. ive tapped their mouths and hands. no luck. idk what to do
