Parenting and grandparents

Do you think because of the respect you have for your parents they don't properly allow you to discipline or to correct your children?

I know grandparents love grandchildren but sometimes I feel like they think these children are a fresh start or like it there own children and they meddle in everything it's like grandparents are there for giggles but I wish they were there to help teach them good things good manners and read them a book, play with them instead it's like run free eat all the sugar you want and at the end I will tell your mom everything bad you did but tell her she's not raising them right but also tell her it's okay don't discipline the kids don't tell them anything they are so good, then later grandparents pick your parenting apart and say if those were my kids and I would have raised them better do you want me to take them in?

Yet it's all this criticism oh your house should be clean it's no excuse you have kids you have to clean up after them the same day a mess is made the same day you clean it up you can't leave it there to when you get to it otherwise the house will look like a tornado ran through

So I'm a bit overwhelmed with all these comments and judgement it's like I feel they love my kids but pick me apart and I'm there own child. I don't know what to do or say to them
