all i can remember from this movie is a singing competition, the plot revolves around 3 or 4 siblings (a boy and 2 or 3 girls) who are trying to enter it.
i also remember the movie starts with the children cooking breakfast for their mother.
it was released in the late 90’s early 2000s.
i know the info i gave you isn’t a lot but thats all i can remember and its been killing me.
thank you
sounds like “The Right Connections” to me.
