I am the only heir to my father. I have son who is still an infant. My question is as per the Hindu

I am the only heir to my father. I have son who is still an infant. My question is as per the Hindu Succession Act is there a provision to prevent my sons/daughter getting share of my father/their grand father's property? After his succession? Facts; My father is 78 years old My Mother is 75 years old Majority of his property is self acquired/self earned? There may be few acres of land which he would have inherited from his father. Myself, I am the only son to my parents 33 years old married to my wife who is 29 years. No family problems what so ever. I have a son who is 2.5 years old. The above questions has been asked without any ill feelings towards my wife or children or my parents. The intention here is to ensure that my father's property should not create any dependency on kids & I want them to be independent individuals before they get a share in their grand parents property. so that my father/mothers hard earned money/property does not get misused by my children. Your valuable advise on the above question would be of great help.
