Mil and alĺlll

Baby is 19mths old . She could roughly understand what is going on through our action and some key words . When brought to mil place , sometimes she would jokingly or wanna try to scare my child by using the cane to hit on something and telling her she would beat . Can tell that she is afraid and i do not want her to get the ideal of her not doing something wrong and mil want to beat her and so on ... i do not like it and do not want to introduce violence to my child at such at young age especially she doesnt really understand everything . She would also start to do this hitting and scolding action when my child start to whines when shes feeling scared and cranky at her place . And secondly , my child will imitate and do this to her friemd in playground. And it happens before , luckily the parents of the kids is understanding despite there were injuries. But i guess she just dont understand ... my husbamd know what i dislike but just turned to me to look at my reaction . He is just happy tht his mother playing with her. And they also encourage habit like watching tv , and phone to her when at home i does not even allowed her to start such a habit for her own good . Husbamd does not try to stop even though he knows all these . In the end , all the taking care of the child and consequemces i have to bare in raising the child . They just spoilt the child just like that . Mqybe they think its nothing , but in the long run its gonna leave an impact ... Somehow i think mil knows becus she always look at my facial expressiin and telling me she just playing with her amd so . I just did not smile and show im unhappy ahout this type of behavior everytime she does this . When baby cry , she will just say , oh mybe shes hungry , u didmt feed her enough milk or ask me bck what happen... Ive to take care of my child all the way for several hours , while husband just lays around the house . So on sunday , ive to cleaned up my house and all the laundry and tale care of my kid and all to prepare for monday working . Im really tired.... And husband refuse to go bck to my parent house. And fair enough alternate week to g back to own parent house together? But it seeems like every week to his mum place .. This makes me really reluctant to go to mil place everyweekend... What can i do ahout this ? ...
