A baby girl and her two older siblings are missing after they were last seen four days ago in suburban Melbourne.

Five-month-old Bella, Brayden, two, and Brooke James-Fielding, 11, were last seen at Narre Warren on Friday, with their parents telling police the children are being cared for by friends in NSW.

Police on Tuesday released images of Brooke and Brayden in the hope someone has information regarding their whereabouts.
