What is the name of the movie?

I saw this movie years ago and I think it was made in the 90’s. There was a mom who had mental illness and there episodes. Either she was good or bad. When good she tried to make up for the bad. I remember one scene where she goes up in a single engine plane but cannot remember if one of the kids was with her. I remember another scene of her yelling at the children. I believe there was a father who was away on business a lot.
