I been living with my wife's family for a while and before birth of my kid and after kid, his grandmother feels like she is right about everything.

My Mrs is also a way of nagging what she thinks is right and I think it's very annoying when you they keep proving you wrong. Her grandma just pops in room in middle of night or early morning if baby start crying, which again in my opinion is very very foolish and evading privacy.

Same issue is with her brothers too, they just keep on saying like my Mrs isn't taking care of the baby. Is the environment intoxicating or they want to owe baby life?
As such I feel I don't have control of being baby dad and loosing control.

  Hence the question, how to stop grandparents from being overprotective?

I have been living with my wife's family for a while both before and after the birth of my kid, and my mother-in-law feels like she is right about everything.

My wife is also a way of nagging what she thinks is right and I think it's very annoying when you they keep proving you wrong. Her grandma just pops in room in middle of night or early morning if baby start crying, which again in my opinion is very foolish and invading privacy.

Same issue is with her brothers too, they just keep on talking like my wife isn't taking care of the baby. Is the environment toxic or do they want to own the baby's life? 

I feel I don't have control of being the baby's dad and I am losing control. Hence the question, how to stop grandparents from being overprotective?
