For the points below, I will suggest based on what I would have done. Do understand that parenting varies from person to person. First of all, will figure out why she takes that decision n what makes her think that she has to take that decision that am not going to eat or do anything. Solution: ‘whenever you take a decision to not eat or do anything. I will make it a plus one, so it’s not one day, it will be two days where you will starve, away from any snacks for 4 days n not do anything means, standing in that corner or jus sitting. Not doing anything right, so be still.’ Figure out if there’s anything she likes more, gadgets, toys, anything. Take those away. N mom n dad not talkin, make it bigger impact like not taking her out or cutting some privileges. Ignoring the tantrums, even a hundred times is the only way out. Why I say hundred times, because she already saw the result, she wins, to change this mindset it takes a bit longer period. Not right attitude. Parents are everything to the kids. If we give up, it’s only downhill for the kids from there. Don’t do that. Change your parenting style. Disciplining kids doesn’t mean hitting them, abusing, yelling, belting, or anything like that. It’s about taking a stronger stand n teaching them what’s right n wrong. N ensuring we find a way to make them listen to us.
