PRIVATE PRE SCHOOL? 4 BOYS?? PARENTS NOT APOLOGIZING AND TEACHER WAS LAME DUCK??!!! Omg I would be so po'ed.
My daughter was at a private preschool last year. The kids were spoiled and bratty. This year, she's at a Christian school. The parents are more working class and strict. The kids are WAY NICER. But at any rate, I hear you on not being able to switch right now.
I already taught my kids (daughter almost 5, son almost 3) how to handle bullies, and so far they both do it. And I'm planning to keep close tabs for as long as they're in school.
I started when my son was barely 2 1/2. There was a 3 year old hitting him frequently in my gym daycare. My son is very disciplined and knows not to hit, whereas this kid would just get time outs and continue hitting. It really hurt me to see my son getting hit and crying. So I explained to him how to hit back. Not kidding. We had a game, where I told him to hit back and yell "Stop it!!!" and we practiced on each other. He still looked sort of scared of the kid the next time we went, but I reminded him at the daycare (in front of the mom) "Remember, hit him really hard if he hits you and be sure to yell STOP IT just like we practiced." She gave me a dirty look. WHATEVER. I smiled at her. She quit coming after her son hit a newborn in the face with a toy and her dad flipped out.
For my daughter, when she was about 3, a girl was bossing her around at the park. Forcing her to play some game and chiding her about being slow and yanking her around. My daughter was getting teary eyed and didn't want to play, which I was prepared to ignore-all in a day's fun after all, don't want to be a hover mom, but I noticed my daughter looking insecure, like she felt she had to do what the girl said, and I knew she needed to learn to stand up for herself. The girl's mom was texting. I called my daughter over (again, ear shot of the mom) and said, "Ok, see how that girl is not playing nicely and she's bossing you around? You do NOT have to play with her. Just say NO!!! and run away." The girl continued to grab my daughter's jacket and yank her, and I said, "Go ahead and push her back and tell her to 'Stop it'." The mom never looked up from texting, but my daughter looked hugely relieved to yell "NO!" and run away.
Ever since then we have frequent talks abut how if they see anyone being mean they should yell right away, push or hit back, and most importantly, go to the side of someone being pushed around by a bully and make sure they are OK and NEVER join in with someone being mean. I always ask if she saw anyone being mean at daycare. Who's mean, does she make sure to yell at them etc.
We have to start the message very young. lots of kids out there are not disciplined and the rate of bullies has skyrocketed even in nice schools since kids have no fear of parents, teachers etc. Kids have to learn not to be targets and to recognize and stand up to bullies and defend each other.
And heck ya, that teacher would be on my major sh--list and she would KNOW it. I would not worry about offending her. I would make it clear I had better not hear of any bullying being enabled because I would take it as high as it could go. I would even speak to those boys directly (They're 4, not teenagers). I would let the teacher know (don't ask, just do it) that I was going to have a word with them, I would go up calm, cool, friendly, not angry in case they tell their mom, and I would say, "Hey, dudes, I hear you guys are super tough guys and like to be mean to people sometimes. Don't bother my son please. If I hear that you keep doing it, I will tell your parents until they care. Thanks, have a nice day." Do it so the teacher hears you. If your son also yells at them and strikes back, and the teacher has taken you seriously, at 4, no major damage will have been done and it should improve.
I also believe that when our kids see us sticking up to people, they learn not to just feel bad and let things slide, which is human nature. As they get older they have to fight their own battles, which is what I'm trying to teach, but at 4, you should defend your son. Good work telling the parents. Don't be afraid to speak up again. They're totally lame. Don't have any guilt. If someone told me one of my kids was bossing someone around, believe me I would handle it and want to know. There is no excuse for their reaction.
