I have read that it is the moon that prevents the earth from flipping. Our moon is the largest in relation to its planet in the solar system. Earth and the moon are effectively linked by the gravitational attraction between them and this acts to stabilise the axial tilt.
Venus has no moon and has flipped in the past so that it rotates retrograde.
