I usually believe that children act what they experience. She's seen aggressive behavior somewhere, just because she is good at the daycare doesn't mean all the other children are!! I really had to work on my little one, as a single parent I had to work, and daycares will contribute to making a child aggressive because the 'workers' hands are tied except for time outs to deal with aggressive behaviors from the children.
I've never felt to hit them and then tell them not to hit made much sense anyway (how confusing to a little mind). But I did what I called controlled spankings. WITHOUT ANGER OR ANY TYPE OF DISCUSSION JUST QUIETLY put them over my knee, pull down their little britches and slap their but cheek. I never hit or used a lot of force just a good stinging slap along with an explanation of the bad behavior and a little time in a chair to enforce the seriousness of the action. That's about as extreme as I ever had to go. We've always called them grandma spankings cause that's what my grandma did and my siblings and I did not misbehave when Nana was around, ever. She slapped with the ends of her fingers and OUCH!
But some people don't believe in this type of discipline and I'm sorry to say this, because I am very open minded and a peaceful person, but parents need to draw a line or else how are kids to know when they cross it?? NO NO just doesn't cut it!
Then parents turn around and get on to the kids for saying NO instead of teaching them when it is appropriate! Makes the children unable to stand up for themselves later on at school and difficult situations because they've had it pounded into their brains to not be disagreeable. Sorry got way off the subject there.
Pulling her hair or reacting in the same manner does not put YOU in charge or control, and controlling bad behavior isn't done with bad behavior, (that's how WARS are started).
