Have you pinpointed which resident girls are the problem? What behaviours are you seeing?
Any blood?It's 2 of the girls. They corner them and try and dominate them. They pin them down until they cry They are super rough. We've tried to have them play together 5 times already.
Well then give us the details...pinning, chasing, screaming? what? If there's no blood I wouldn't worry anywhere near as much.no blood, just harassment.
