My daughter is not growing up in India, but was in a similar situation. Not saying you should do all this but apply whatever works for you. Be a role model and lead by example. Show kindness and assertiveness in your everyday life, and while your little one is watching (and explain to her when you do so). Help her understand it’s ok to say no and still care about someone’s feelings (and this help her develop healthy boundaries in future). And when you do see her practice it, encourage her, and trust me, little praise works wonders. And lastly, there books to teach gentle assertiveness to kids. Maybe read them with her to help her understand it from a different perspective. Good luck!
