little stranger(redirected from a little stranger)
A baby or very young child that is new to someone's life, especially parents or siblings. While the arrival of a new baby is usually a very happy event for most first-time parents, it can also be incredibly overwhelming and at times unpleasant bringing a little stranger into one's life and home. Siblings over the age of three have a hard time in particular accepting the little stranger who now takes away the attention from mommy and daddy.
