As a mom of a child that hits. I know it’s bout your responsibility but you could also help mom teach her child bout hitting. My daughter was the same way she want good at expressing feelings and when she was mad or overwhelm she would hit. Doctors told me when we see her getting to that point to hug her warm embrace but also hold her hands while. Even doing that she still hit. Her cousins didn’t want to play with her, her classmates was scared of her, school didn’t let her do anything. I put shows on to help her express emotions. But once I start getting more ppl in my village and she started learning sign language the hitting got better and then she stopped. My opinion they just need time and people in the corner they are tiny with emotions and some just don’t know how to handle it. What also helped me is doing alone time, if I see l little one getting upset I’ll let her draw alone, or breathing exercises, or sometimes I act hurt (she has also hit me and her father)
Sit down with ur friends express how u feel but ask her if there is any way. My bby girl is very selfish and can sometimes mean lol but the more people that was helping trying to teach her also bout hitting and how it makes others feel it definitely got better.
To be honest they sound like siblings! My daughter is 6 months older then her cousin . They are like best friends but some days they just bother each other . They are so close they act like siblings , they are also 3!. We went to my parents together with the kids and my nephew was constantly pulling my daughters hair or doing something and she was just over it . It did bother me because he wouldn’t listen when she told him to stop or when I would tell him to . I think what you’re doing now is good honestly . I don’t think you should stop being friends or stop letting them be around each other . But respecting his wishes when he doesn’t want to play is important! Also maybe following them when they leave the room might help too so you can keep an eye on the situation . I hope your friend talks to her daughter when she does hurt him and explain to her it’s not okay to hurt others . I can see how if it happens every time that you wouldn’t want them around though .
