My 2 Year Old Gets Bullied Often

If all else fails, you can try a different playspace.
Some kids, especially boys just don't respond to "explaining", even at an older age than 5! My boys were 7 or 8 before I could get them to listen on a regular basis, and have any self control at all. They were not "bad", just unable to take someone else's perspective, and see how their behavior affected others.
I this case I would not call it bullying, but "aggressive behavior". Kids who have a lot of siblings, or older brothers, are more likely to be loud or forceful, I think, because otherwise they know they will never get anything. An only child who is a girl and sensitive by nature...you can't compare other kids to her.

along the lines of the dog park story, I just kept thinking as I read your post that the park where you are playing is not appropriate for your daughter. Many times there are "tot" climbers, with separate areas for kids over 5. I can't think of any park I frequented when my kids were that young when they had THAT many troubling interactions with bigger kids. She's such a peanut, under 3 and small for her age, that it would be in your best interest and hers to either seek out another place to play or adjust the times you go there to avoid the crowd of unruly bigger kids.

if you are already in the tot area and the 5 year old is running rampant, you can and should speak to him to say "this area is for the little ones, please keep your playing on the bigger structure."

J.,

I use to have two dogs, a big chocolate lab and a little terrier. They grew up together and were great pals. I could take them to the dog park and they both played well with other dogs, large and small.

When my lab died, my little terrier still wanted to play with all the big dogs…. the bigger the better. However, some of the big dogs weren’t so gentle with him and he got stepped on every now and then.

I had two choices:

1. A dog park with two sides; one that accommodated small dogs and one that accommodated big dogs.

Or

2, Keep on going to the same park we always went to and let him adjust.

When I took him to the park with two sides, he always wanted to go to the big dog side. He didn’t like being isolated with only small dogs like him.

This is meant to be a parable, but to make a long story longer, I think you may be over reacting a little…. that’s normal especially for a first time parent. The larger issue I hear is that you have problems with people who do not speak the language you speak.

A good parent or care giver, no matter what language they speak can see if children at play need a little attention and/or correction. If you see something going on and the other adult does not, it would be fine for you to say something or remove your little one if you feel she is in danger.

I don’t think a letter to an English-speaking parent would be rude. I do think it would be a bit overboard and not necessary.

If I were you, the next time the child bullies your daughter, you go over to him, tell him, "NO!", and tell him "you do not bully other children," sternly, the way you would do it to your own child.

If his mom isn't present or isn't teaching him properly, then it is up to someone else to teach him. You will be doing him a favor in the long run. Think of it as "It Takes a Village."

And I agree with Toni. You don't need to send a letter, just do it yourself. Kids usually listen to someone else more than their own parents anyway. Probably the mom will be happy to have you do it for her - she's obviously busy. I was personally always happy to let someone else discipline my child (short of hitting them) for a while so I could relax.

p.s. - It will take a long time because of your daughter's passive nature, but I would start teaching her that she doesn't have to apologize when someone else hurts HER. It's not healthy to go through life being more concerned with everyone else's feelings than your own, and letting people walk all over you. She needs to learn that she has rights, too. Take that advice from someone who let people step on her without comment for most of her life.

Boys, in particular, just play rougher. It may seem aggressive, but often it truly is boys being boys. And older kids often don't pay attention to younger kids and bump into them or do things they shouldn't. At five, you still can't reason with many kids. If the "bully" child is extreme, he may have a disability that isn't readily apparent, such as ADHD, that causes the behavior. As much as parents may work with kids to encourage and teach proper behavior, parks are often an outlet for excess energy and you may see more of the bad behaviors come out.

I found that when my kids were young, I would just stick to parks with much smaller play structures that didn't interest older kids. That eliminated many situations where I'd have to worry about the behavior of older kids. You might temporarily change parks to avoid the child you mentioned so you don't have to face the problems constantly.
