There's a movie where a mother takes her kids to live with her grandmother. The grandmother convinces the mother to continually drug the kids. They take all the shoes and put broken glass around the house so they can't escape. Very old movies from the 90's. Eventually kids escape can anyone tell me the name...

I don't recall anything about broken glass, but it sounds a lot like this:
Flowers in the Attic (1987)
Starring Kristy Swanson, Victoria Tenant, Louise Fletcher
IMDb synopsis:
After the death of her husband, a mother takes her children to live with their grandparents in a huge, decrepit old mansion. However, the children are kept hidden in a room just below the attic, visited only by their mother, who becomes less and less concerned about them and their failing health and more concerned about herself and the inheritance she plans to win back from her dying father, to the point of murder.
