So, this is the second time i am posting this thread as i think the issue is getting out of hand. My nephew is 2years2 months old. Very smart,stubborn. Understands everything.also very naughty. Purposefully throw things. Sometimes from the balcony. Cries uncontrobally when confronted. His mother is a totally irresponsible woman. We live in 1st floor and they live in ground floor. She will send him off to our home alone i.e she wont come. Her husband(my cousin) does all the hoysehold chores except cooking. My sil will cook simple meals twice a day which takes about 2 hours a day for her. When i am unable to control his tantrums i go and leave him at his home but my sil will again send him upstairs after an hour or something. But she herself wont come. She is on cellphone all day watches all the tv serials and youtube vlogs. Only the time he is sleeping, he is at his home. I cant say to her face diectly that dont send ur son to our home.although i have told her multiple times that he throws things around and break. Just for the sake of it she will scold him. But thats it.never tried to discipline him. My parents are soft natured. They dont want to be rude to her. So ladies pls tell me how do i handle her without using harsh words. I want to set boundaries but have no idea how to do it.
