Sandra Bullock -- The Sunny Side of Parenting

Sandra Bullock spent some quality time with her step-daughter in Huntington Beach yesterday -- proving yet again that her "commitment" to 5-year-old Sunny James is rock solid.

Just last month, Bullock -- star of "The Blind Side" -- and her husband Jesse James were awarded full custody of Sunny after a nasty dispute with Jesse's ex, Janine Lindemulder.

Last year, Sandra had fired off a letter to the judge saying, "I know the term 'stepmother' carries many connotations, one of them being a 'glorified babysitter' ... My commitment and responsibility to Sunny ... goes beyond that."

It appears Bullock doesn't just talk the talk ...
